An efficient synthesis of 6H-isoindolo[2,1-a]indol-6-ones through rhodium-catalyzed NH-indole-directed C-H carbonylation of 2-arylindoles with carbon monoxide has been developed. Preliminary mechanistic studies revealed that this reaction proceeds via N-H bond cleavage and subsequent C-H bond cleavage. Reaction monitoring via ESI-MS was used to support the formation of five-membered rhodacycle species in the catalytic cycle.

The rate of alkaline hydrolysis of the novel compound 2-(3-nitrophenoxy)quinoxaline 1 increases with increasing head group size in a series of cationic micellized surfactants (C16H33NR3Cl and C16H33NR3OH: R = Me, Et, n-Pr and n-Bu). The reactivity increase with increasing head group size is related to the disruption of the hydration of hydroxide ion.

Drug candidates for inhibition of HIV-I replication can target Src family kinases (SFK), such as Hck, that interact with Nef protein of the virus. Compounds characterized by such inhibitory activity were identified via an assay for kinase activity of an SFK in a Nef:SFK complex. Illustrative of inhibitors identified using the kinase assay are various 2,3- diaminoquinaxolines and furo[2,3-d]pyrimidines. The inventive inhibitors were found to arrest HIV-I viral replication in vitro.

Attempted dehydrogenative cyclisation of 2-chloro-3-(2′- benzylidinchydrazino)quinoxaline 5 with a view to prepare 1-phenyl-4-chloro- [1,2,4]-triazolo [4, 3-a]quinoxaline 6 using cupric acetate gives 1-phenyl-4- oxo-[1,2,4]triazolo[4,3-a]quinoxaline 7. A rational explanation is offered for this reaction and the applicability of cupric acetate as dehydrogenative cyclisation agent (such as in the conversion of 10?11) has been demonstrated.

The paper presents experimental data regarding a number of seven new benzimidazo[2,3-d]thiazolo[4,5-b] quinoxaline dyes have been synthesized by condensation of 2,3-dichloroquinoxaline with different 1,3-dihydro-2H- benzimidazole-2-thione derivatives. Reaction products were purified and characterized by means of elemental analysis, UV-VIS, IR, 1H and 13C-NMR, mass spectra and thermal analysis. Structure-property relationships in the dyes are discussed with respect to the nature of the substituents in the benzimidazole moieties.

A novel one-pot reductive methodology for the synthesis of optically pure tert-butylmethylphosphine-borane is reported. The preparation uses as the starting material tert-butylmethylphosphinous acid-borane, which is available in both enantiomeric forms from cis-1,2-aminoindanol and tert-butyldichlorophosphine. The process is based on the reduction of a mixed anhydride, the configurational stability of which has been studied in several solvents and temperatures. Tetrabutylammonium borohydride was the best reducing agent allowing for the development of a practical process. To demonstrate the utility of the new methodology, the product obtained in this manner was used in the preparation of Quinox-P?.
