Synthesis of heterocyclic allenes via palladium-catalyzed hydride-transfer reaction of propargylic amines

(Chemical Equation Presented) Propargylic diisopropylamines containing heterocycles, which were prepared readily from heterocyclic bromides and propargyldiisopropylamine by the Sonogashira coupling reaction, underwent the allene transformation reaction in the presence of Pd2(dba) 3¡¤CHCl3 catalyst (2.5 mol %) and 1,2-bis[bis(pentafluorophenyl)phosphino]ethane (10 mol %) at 100C in CHCl3, giving the corresponding heterocyclic allenes in good to high yields via the palladium-catalyzed hydride-transfer reaction.

New approaches to the synthesis of pyridinium N-heteroarylaminides

Different substituted pyridinium N-heteroarylaminides have been prepared in one step from N-aminopyridinium iodide and the corresponding heteroaryl halide by two alternative routes. The use of Pd catalysis allowed the easy preparation of products from the less reactive haloheterocycles. The use of water as a solvent in conjunction with microwave heating dramatically diminishes the reaction time without having an adverse effect on reaction yields.

Metal-Organic Framework Magnets

Metal-organic frameworks represent the ultimate chemical platform on which to develop a new generation of designer magnets. In contrast to the inorganic solids that have dominated permanent magnet technology for decades, metal-organic frameworks offer numerous advantages, most notably the nearly infinite chemical space through which to synthesize predesigned and tunable structures with controllable properties. Moreover, the presence of a rigid, crystalline structure based on organic linkers enables the potential for permanent porosity and postsynthetic chemical modification of the inorganic and organic components. Despite these attributes, the realization of metal-organic magnets with high ordering temperatures represents a formidable challenge, owing largely to the typically weak magnetic exchange coupling mediated through organic linkers. Nevertheless, recent years have seen a number of exciting advances involving frameworks based on a wide range of metal ions and organic linkers. This review provides a survey of structurally characterized metal-organic frameworks that have been shown to exhibit magnetic order. Section 1 outlines the need for new magnets and the potential role of metal-organic frameworks toward that end, and it briefly introduces the classes of magnets and the experimental methods used to characterize them. Section 2 describes early milestones and key advances in metal-organic magnet research that laid the foundation for structurally characterized metal-organic framework magnets. Sections 3 and 4 then outline the literature of metal-organic framework magnets based on diamagnetic and radical organic linkers, respectively. Finally, Section 5 concludes with some potential strategies for increasing the ordering temperatures of metal-organic framework magnets while maintaining structural integrity and additional function.

2,2?-Homocoupled Azine N,N?-Dioxides or Azine N-Oxides: CDC- or SNAr-Controlled Chemoselectivity

An unprecedented Cu(OAc)2- and LiOtBu-mediated homocoupling of azine N-oxides to yield 2,2?-azine N,N?-dioxides is reported. This is the first instance in which copper has been used to catalyze the homodimerization reaction, especially of 2-phenylpyridine N-oxides. In the absence of catalytic copper, the reaction follows an alternative pathway, and instead of dioxides it yields 2,2?-azine N-monoxides. This latter protocol works efficiently with a range of N-heterocyclic oxides of pyridine, 2-phenylpyridine, quinoline and N-aryl-1,2,3-triazole. It is scalable, offers high regioselectivity and gives the products in moderate to high yields. The observed chemoselectivity between the copper-assisted and copper-free protocols is routed through oxidative cross-dehydrogenative coupling (CDC) and nucleophilic aromatic substitution of hydrogen (SNAr) pathways, respectively.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1532-72-5, help many people in the next few years.Application In Synthesis of Isoquinoline N-Oxide

Modulation of Methylene Carbon Response Intensity in Long-Range Heteronuclear 2D NMR Chemical Shift Correlation Spectra

Several recent papers have dealt with the modulation of protonated carbon response intensities in long-range heteronuclear 2D NMR chemical shift correlation spectra.Expressions describing the one-bond modulation of the response intensity of the C-3 methylene resonance of 6,7-dimethoxy-3,4-dihydroisoquinoline, and the decoupling of this modulation afforded by a BIRD pulse located midway through the Delta2 refocusing delay, are presented with experimental confirmation.Long-range response intensities are related to the conventional heteronuclear chemical shift correlation spectrum optimized for transfer from the directly attached proton.KEY WORDS: two-dimensional NMR; 2D-NMR; long-range heteronuclear correlation; response intensity modulation; modulation decoupling.

Applications of Palladium-Catalyzed C-N Cross-Coupling Reactions

Pd-catalyzed cross-coupling reactions that form C-N bonds have become useful methods to synthesize anilines and aniline derivatives, an important class of compounds throughout chemical research. A key factor in the widespread adoption of these methods has been the continued development of reliable and versatile catalysts that function under operationally simple, user-friendly conditions. This review provides an overview of Pd-catalyzed N-arylation reactions found in both basic and applied chemical research from 2008 to the present. Selected examples of C-N cross-coupling reactions between nine classes of nitrogen-based coupling partners and (pseudo)aryl halides are described for the synthesis of heterocycles, medicinally relevant compounds, natural products, organic materials, and catalysts.

Structure-activity study of 2,3-benzodiazepin-4-ones noncompetitive AMPAR antagonists: Identification of the 1-(4-amino-3-methylphenyl)-3,5-dihydro-7,8-ethylenedioxy-4H-2,3-benzodiazepin-4-one as neuroprotective agent

In the search for AMPA receptor (AMPAR) antagonists, 2,3-benzodiazepines represent a family of specific noncompetitive antagonists with anticonvulsant and neuroprotective properties. We have previously shown that 2,3-benzodiazepin-4-ones possess marked anticonvulsant properties and high affinity for the noncompetitive binding site of the AMPAR complex. In this paper, we report the synthesis and pharmacological characterization of a full set of 2,3-benzodiazepin-4-ones in order to better define the structure-activity relationship (SAR) of this class of compounds. Binding assays and functional tests were performed to evaluate the antagonistic activity at the AMPARs. Through these results we have identified a potent AMPAR antagonist, 1-(4-amino-3-methylphenyl)-3,5-dihydro-7,8-ethylenedioxy-4H-2,3-benzodiazepin-4-one (5c). This compound noncompetitively inhibited AMPAR-mediated toxicity in primary mouse hippocampal cultures with an IC50 of 1.6 muM and blocked kainate-induced calcium influx in rat cerebellar granule cells with an IC50 of 6.4 muM. Thus, 5c has the in vitro potential as therapeutic drug in the treatment of various neurological disorders.

Diastereoselective synthesis of epoxide-fused benzoquinolizidine derivatives using intramolecular domino aza-Michael addition/Darzens reaction

An efficient and diastereoselective strategy based on an intramolecular domino aza-Michael/Darzens reaction to synthesize epoxide-fused benzoquinolizidines has been described. Three bonds (1 C-C, 1 C-N and 1 C-O), three rings and three chiral centers can be constructed in a single pot under very mild conditions. All the products were isolated in only one diastereomer with 40-80% yields.
