An organocatalytic enantioselective direct alpha-heteroarylation of aldehydes with isoquinoline: N -oxides

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.category: Isoquinolines, you can also check out more blogs about1125-80-0

Synthesis of biheteroaryl derivatives by tetraphosphine/palladium-catalysed Suzuki coupling of heteroaryl bromides with heteroarylboronic acids

The synthesis of biheteroaryl derivatives by palladium-catalysed Suzuki cross-coupling reaction of heteroaryl bromides with heteroarylboronic acids is a challenging reaction due to the electronic and/or poisoning properties of these heteroaryl compounds. Through the use of [PdCl(C3H5)]2/cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane as a catalyst, a range of heteroaryl bromides undergoes Suzuki reaction with heteroarylboronic acids such as thiophene-, furan- or pyridineboronic acid derivatives in good yields. This catalyst can be used at low loadings with several substrates. In general bromopyridines were found to be more reactive than bromothiophenes or bromofuranes.

INTERMEDIATES USEFUL FOR MAKING TETRABENAZINE COMPOUNDS

A method of preparing a tetrabenazine compound (TBZ compound) having structure I comprising the steps of reacting a nucleophilic alkenyl species with aldehyde compound II and oxidizing the resultant allylic alcohol to provide enone III. The protecting group P1 on the tetrahydroisoquinoline nitrogen is removed and the resultant deprotected intermediate is induced to undergo an amino cyclization reaction to provide a product TBZ compound having structure I. The method may be used to prepare either enantiomeric form of tetrabenazine; (+)-tetrabenazine or (?)-tetrabenazine. Alternatively the method may be adapted to provide a mixture enriched in one tetrabenazine enantiomer, a racemic mixture, or a diastereomeric mixture of tetrabenazine compounds. In addition, the present invention provides novel synthetic intermediate compositions which may be used to prepare either or both enantiomers of tetrabenazine, derivatives of tetrabenazine, and analogs of tetrabenazine.

Palladium(II)-catalyzed C-C and C-O bond formation for the synthesis of C1-benzoyl isoquinolines from isoquinoline: N -oxides and nitroalkenes

C1-Benzoyl isoquinolines can be generated via a palladium(ii)-catalyzed C-C and C-O coupling of isoquinoline N-oxides with aromatic nitroalkenes. The reaction proceeds through remote C-H bond activation and subsequent intramolecular oxygen atom transfer (OAT). In this reaction, the N-O bond was designed as a directing group in the C-H bond activation as well as the source of an oxygen atom.

Comparative molecular field analysis (CoMFA) models of phenylethanolamine N-methyltransferase (PNMT) and the alpha2-adrenoceptor: The development of new, highly selective inhibitors of PNMT

As a guide to the development of new and more selective inhibitors of phenylethanolamine N-methyltransferase (PNMT) vs the alpha2-adrenoceptor, we have performed a comparative molecular field analysis (CoMFA) on a series of 80 benzylamine analogues. Using the models obtained, we have proposed a series of 3-trifluoromethyl-1,2,3,4-tetrahydroisoquinolines and predicted the activity of other analogues.

Synthesis, structure-activity relationships, and antitumor studies of 2-benzoxazolyl hydrazones derived from alpha-(N)-acyl heteroaromatics

Recently we have described the antitumor activities of 2- benzoxazolylhydrazones derived from 2-formyl and 2-acetylpyridines. In search of a more efficacious analogue, compounds in which the 2-acetylpyridine moiety has been replaced by 2-acylpyridine and alpha-(N)-acetyldiazine/quinoline groups have been synthesized. The 2-acylpyridyl hydrazones inhibited in vitro cell proliferation in the nM range, whereas the hydrazones derived from the alpha-(N)-acetyldiazines/quinolines inhibited cell growth in the muM range. Compounds tested in the NCI-60 cell assay were effective inhibitors of leukemia, colon, and ovarian cancer cells. E-13k [N-benzoxazol-2-yl-N?-(1- isoquinolin-3-yl-ethylidene)-hydrazine] inhibited the proliferation of MCF-7 breast carcinoma cells more efficiently than nontransformed MCF-10A cells. It is not transported by P-glycoprotein and a weak MRP substrate. Increased concentrations of serum or alpha1-acid glycoprotein did not reduce the antiproliferative activity of the compound. In the in vivo hollow fiber assay, E-13k achieved a score of 24, with a net cell kill of OVCAR-3 (ovarian) and SF2-95 (CNS) tumor cells.
