Ir(III)-Catalyzed Oxidative Annulation of Phenylglyoxylic Acids with Benzo[ b]thiophenes

An Ir(III)-catalyzed oxidative annulation of phenylglyoxylic acids with benzo[b]thiophenes for the construction of benzothieno[3,2-c][2]benzopyranones in one step is disclosed. Three C-H cleavages and C-C/C-O bond formations are involved in this reaction. This protocol features a relatively broad substrate scope, good functional group tolerance, good regioselectivities, mild reaction conditions, and scale-up synthesis.

Alkyl phenylglyoxylates as radical photoinitiators creating negative photoimages

Alkyl phenylglyoxylates are shown to be efficient photoinitiators for acrylate polymerization. Benzoyl and phenyl radicals derived from intermolecular hydrogen abstraction are the initiating species. A negative photoimage system was developed based on thi

Controlled meta-Selective C-H Mono- And Di-Olefination of Mandelic Acid Derivatives

Mandelic acids represent a key structural motif present in many drug molecules. Herein, we report the controlled meta-selective mono- and diolefination of mandelic acids by the careful design of the substrate and oxidant. Furthermore, free meta-functional

REARRANGEMENTS OF AROMATIC CARBONYL ARYLHYDRAZONES OF BENZENE, NAPHTHALENE, AND AZULENE

Aromatic carbonyl arylhydrazones have been shown to undergo two kinds of rearrangement in polyphosphoric acid both involving nitrogen-nitrogen bond cleavage.The first proceeds via insertion of the imine portion in the position ortho to the second nitrogen atom to give o-phenylenediamine intermediates: their evolution depends on the nature of the starting substrate.This reaction has been employed for synthesizing the quinoxalines (5) and the phenanthridines (11), and was demonstrated to be intramolecular.The second reaction path is a sigmatropic rearrangment exclusive to electron-rich aromatic carbonyl hydrazones.
