One-pot, three-step copper-catalyzed five-/four-component reaction constructs polysubstituted oxa(thia)zolidin-2-imines

A novel one-pot synthesis of polysubstituted oxa(thia)zolidin-2-imines has been developed. It employs A3-coupling of aldehyde and amine with alkyne to form propargyl amine, which on (thio)amidation with iso(thio)cyanate produces N-propargyl(thio)urea, and a cyclization reaction. A 5-exo-dig iodocyclization of N-propargylurea constructs 5-iodomethyleneoxazolidin-2-imine, while cycloisomerization of the thio analogue provides 5-methylenethiazolidin- 2-imine. In this process, CuI catalysis has been found to be crucial, and the cyclization occurs through oxygen/sulfur (not nitrogen) nucleophilic attack to alkyne. Georg Thieme Verlag Stuttgart ¡¤ New York.

Discovery of 4-((7H-Pyrrolo[2,3-d]pyrimidin-4-yl)amino)-N-(4-((4-methylpiperazin-1-yl)methyl)phenyl)-1H-pyrazole-3-carboxamide (FN-1501), an FLT3- and CDK-Kinase Inhibitor with Potentially High Efficiency against Acute Myelocytic Leukemia

A series of 1-H-pyrazole-3-carboxamide derivatives have been designed and synthesized that exhibit excellent FLT3 and CDK inhibition and antiproliferative activities. A structure-activity-relationship study illustrates that the incorporation of a pyrimidine-fused heterocycle at position 4 of the pyrazole is critical for FLT3 and CDK inhibition. Compound 50 (FN-1501), which possesses potent inhibitory activities against FLT3, CDK2, CDK4, and CDK6 with IC50 values in the nanomolar range, shows antiproliferative activities against MV4-11 cells (IC50: 0.008 muM), which correlates with the suppression of retinoblastoma phosphorylation, FLT3, ERK, AKT, and STAT5 and the onset of apoptosis. Acute-toxicity studies in mice show that compound 50 (LD50: 186 mg/kg) is safer than AT7519 (32 mg/kg). In MV4-11 xenografts in a nude-mouse model, compound 50 can induce tumor regression at the dose of 15 mg/kg, which is more efficient than cytarabine (50 mg/kg). Taken together, these results demonstrate the potential of this unique compound for further development into a drug applied in acute-myeloid-leukemia (AML) therapeutics.

Highly efficient monophosphine-based catalyst for the palladium-catalyzed Suzuki-Miyaura reaction of heteroaryl halides and heteroaryl boronic acids and esters

A highly active and efficient catalyst system derived from a palladium precatalyst and monophosphine ligands 1 or 2 for the Suzuki-Miyaura cross-coupling reaction of heteroaryl boronic acids and esters has been developed. This method allows for the preparation of a wide variety of heterobiaryls in good to excellent yields and displays a high level of activity for the coupling of heteroaryl chlorides as well as hindered aryl and heteroaryl halides. Specific factors that govern the efficacy of the transformation for certain heterocyclic motifs were also investigated.

Microwave Irradiation for Accelerating Organic Reactions – Part II: Six-, Seven-Membered, Spiro, and Fused Heterocycles

The use of microwave irradiation (MWI) as a nonconventional source of energy, a consequence of converting electromagnetic energy, had become very attractive for its applications to chemistry and material processing. In organic synthesis, the potential of microwave (MW) as a tool for heating attracted much interest soon after the work of Gedye (86TL279) and Giguere (86TL4945) in 1986. The terminology for the introduction of MW for organic reaction enhancement (MORE) and/or MW-assisted organic synthesis (MAOS) enabled access or parallel synthesis of various classes of compounds in organic chemistry. Although in the beginning some obstacles were faced by chemists using this technology, their desire led to the development of methods for the concurrent use of MW. One of these achievements involves the performance of organic reactions under solvent-free conditions: dry media in open vessels. Moreover, equipment and reactors have been developed and have become commercially available. Nowadays, MW activations are widely used in organic chemistry as shown by the increased number of publications. Available reviews include (91OPP683, 95AJC1665, 95T10403, 97CSR233, 97MI1, 98CSR213, 98CJC525, 98S1213, 99AJC83, 99JHC1565, 99MI1, 99MI2, 99MI3, 99T10851, 00CSR239, 00MI1, 01MI1, 01MI2, 01T4365, 01T9199, 01T9225, 02ACR717, 02MI1, 02MI2, 02MI3, 02T1235, 03MI1, 03MI2, 04H903, 05AHC1). The rapid expansion and popularity of assisting a wide range of organic reactions by exposure to MW have been accompanied by achieving reactions under solvent-free conditions, reducing reaction times, and increasing the yield of products and even selectivity. Moreover, in addition to the economic impact, there are additional advantages such as the use of noncorrosive, inexpensive, and environment-friendly catalysts, thus leading to eco-friendly approaches known as “green chemistry”. All these have attracted our attention to review the available literature on the role of MW in the field of heterocyclic chemistry, but owing to the increased number of publications led us first to publish “Microwave Irradiation for Accelerating Organic Reactions. Part I: Three, Four and Five Membered Heterocycles” in a former volume (05AHC1). This new chapter will be the second part including six-, seven-membered, spiro, and fused heterocyclic ring systems. Our survey of the literature on the synthesis and reactions of these heterocycles has been divided according to the number of heteroatoms in the heterocycles. The fused heterocycles are located according to the heterocycle that was built under MWI or as a reaction of these heterocycles acting as precursors. Each type is reviewed by first presenting their methods of preparation of the desired ring followed by its reactions. Heterocycles having either fused benzene or other heterocyclic rings have been located under a separate title when enough literature has been reported.

Quantum mechanical investigation of vibrational and electronic spectra of some 5-substituted isoquinolines

Fourier Transform infrared (FTIR) and FT-Raman spectra of 5-bromoisoquinoline (5-BIQ), 5-aminoisoquinoline (5-AIQ) and 5-nitroisoquinoline (5-NIQ) have been recorded and analyzed. The geometric bond lengths and bond angles have been optimized. The equilibrium geometry, bonding features and harmonic vibrational frequencies have been investigated by ab-initio and density functional theory (DFT) methods. The assignments of the vibrational spectra have been carried out. The calculated HOMO and LUMO energies indicate that charge transfer occurs within the molecule. Stability of the molecule due to conjugative interactions arising from charge delocalization has been analyzed using extensive natural bond orbital (NBO) analysis. Electronic spectral properties have been computed in benzene medium for the three compounds and compared with the experimental values. Thermodynamic parameters such as zero point vibrational energy (ZPVE), thermal energy and specific heat capacity, entropy of 5-BIQ, 5-AIQ and 5-NIQ at 298 K in ground state have been calculated by HF and DFT methods.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C9H6BrN, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1532-97-4, in my other articles.
