A new protocol for the enantioselective direct alpha-heteroarylation of aldehydes with isoquinoline N-oxides, via chiral enamine catalysis, has been successfully developed. High enantiomeric excesses and moderate to good yields were achieved for a variety of alpha-heteroarylated aldehydes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Isoquinoline N-Oxide, you can also check out more blogs about1532-72-5

Substitution reactions of four Pt(II) complexes, namely; N-(2-picolyl)picolinamide-platinum(II) chloride (Pt3), N-(8-quinolyl)pyridine-2-carboxamide platinum(II) chloride (Pt4), N-(8-quinolyl)-3-isoquinolinecarboxamide platinum(II) chloride (Pt5) and N-(8-quinolinyl)-1-isoquinolinecarboxamide platinum(II) chloride (Pt6), were studied with biorelevant nucleophiles, viz. thiourea (TU), N,N?-dimethylthiourea (DMTU) and N,N,N?,N?-tetramethylthiourea (TMTU) under pseudo first order conditions as a function of concentration and temperature using the stopped flow spectrophotometer. The observed pseudo first order rate constants for the substitution reactions obey the rate law kobs = k2[Nu]. The reactivity of the studied complexes depends on strength of pi-backbonding of the attached ligands, which is enhanced by the strong electron withdrawing nature of the carboxamide group on the non-leaving ligands of Pt(II) complexes. Quinoline moieties of Pt5 and Pt6 lie out-of-the square plane, resulting in enhanced reactivity due to the aided entrapment of the nucleophile by the non-planar groups of the ligand. Negative activation entropies and positive enthalpies of activation support an associative mode of activation.

A robust and practical protocol for preparing alkyl aryl ethers has been developed, which relies on using two types of ligands to promote Cu-catalyzed alkoxylation of (hetero)aryl halides. The reaction scope is very general for a variety of coupling partners, particularly for challenging secondary alcohols and (hetero)aryl chlorides. In case of coupling with aryl chlorides and bromides, two oxalic diamides serve as the powerful ligands. The tert-butoxide is first demonstrated as a ligand for Cu-catalyzed coupling reaction, leading to alkoxylation of aryl iodides complete at room temperature. Additionally, a number of carbohydrate derivatives are applicable for this coupling reaction, affording the corresponding carbohydrate-aryl ethers in 29-98% yields.

The goal of current work is to investigate the effect of ethyl group on the electronic, photo-physical and charge transport properties of F-BODIPY, which has been explored at the molecular level after substituting ethyl group at two position of F-BODIPY molecule. In current study; optical, electronic and charge transfer properties for F-BODIPY derivatives (Comp_1, Comp_2 and Comp_3) have been theoretically investigated. All the molecules have been optimized at the ground (S0) and first excited (S1) states using density functional theory (DFT) and time dependent DFT (TD- DFT) with the hybrid functional/basis set (B3LYP /6-31G**), respectively. Effect of ethyl groups at two different positions on the electronic, optical and charge transport properties of 5,5-difluoro-1,37,9-tetramethyloctahydro-1H,5H-514-dipyrrolo[1,2-c:2?,1?-f] [1?3] diazaborinine (Comp_1) as parent molecule has been studied at molecular level. The introduction of ethyl at two positions in Comp_1 led to a red shifted absorption spectra in comparison with parent molecule in the violet region. Various properties of interest such as highest occupied molecular orbitals (HOMO), lowest unoccupied molecular orbitals (LUMO), vertical electron affinity (EAv), adiabatic electron affinity (EAa), vertical ionization potential (IPv), adiabatic ionization potential (IPa), electron reorganization energies (lambdae) and hole reorganization energies (lambdah) were explored. Additionally, global reactivity descriptors e.g. electronic chemical potential (mu), electronegativity (chi), Electrophilicity (omega), hardness (eta), softness (S) and electrophilicity index (omegai) have been calculated theoretically.

Allylmetallation of isoquinolines, quinoline, and quinoxaline with allylic derivatives of zinc was examined for the first time. A convenient procedure was discovered and developed for the synthesis of 1,4-ethano-2,3-dihydroisoquinolines based on the reactions of isoquinolines with allylic derivatives of zinc. This multistage process involves double allylmetallation of the heterocyclic ring followed by cyclization through intramolecular carbometallation of the C=C bond. The structures of three key derivatives of 1,4-ethano-2,3-dihydroisoquinoline were established by X-ray diffraction analysis. The reactions of quinoxaline with allyl-and methallylzinc bromide proceeded stereospecifically to form trans-2,3-diallylated 1,2,3,4-tetrahydroquinoxalines. Heating of quinoline with methallylzinc bromide in THF afforded 4-methallylquinoline in nearly quantitative yield. The initially formed 1,4-metallation product underwent aromatization through elimination of HZnBr.

Analogues of the potent alpha2-adrenoceptor antagonist (8aR,12aS,13aS)-5,8,8a,9,10,11,12,12a,13,13a-decahydro-3-methoxy-12- (methylsulfonyl)-6H-isoquino[2,1-g][1,6]naphthyridine (1b) were prepared and evaluated for alpha1- and alpha2-adrenoceptor affinity. Affinity for alpha2-adrenoceptors was assessed by displacement of [3H]yohimbine from rat cerebral cortical membranes and although 1b and close structural analogues demonstrated high affinity, none were selective for the alpha(2A) or alpha(2B) subtypes reputedly present in this tissue. All of the high affinity alpha2-adrenoceptor ligands were, however, selective with respect to [3H]prazosin (alpha1) binding. Affinity for [3H]yohimbine-labeled alpha2-adrenoceptors was found to be highly dependent on the stereochemistry of the tetracyclic system. The 8abeta,12aalpha,13aalpha diastereomer of 1 (56) had moderate affinity for alpha2-adrenoceptors while the 8abeta,12abeta,13aalpha diastereomer (55) had very low affinity. The affinity and selectivity of these agents for alpha2-adrenoceptors was found to correspond to that observed for several isomeric yohimbine analogues which have similar relative and absolute stereochemistries. Deviation from the structure of 1 by opening the B ring, changing the position of the sulfonamide nitrogen, or changing the attachment of the D ring led to a dramatic decrease in alpha2-adrenoceptor affinity. High binding affinity was found to correlate with functional antagonism in the guinea pig ileum. The reversal of clonidine-induced mydriasis in the rat was used to assess bioavailability and indicated that 1b was a potent alpha2-adrenoceptor antagonist in vivo.
