Regioselective organocatalyzed asymmetric bromolactonization of aryl acrylate-type carboxylic acids: a new approach towards enantioenriched 3-substituted isobenzofuranones
摘要:
The enantioselective synthesis of several 3-substituted isobenzofuranones has been developed through a new and flexible route. When combined with a catalytic amount of benzoic acid, quinidine thiocarbamate bifunctional catalysts have demonstrated their efficiency for the highly regioselective organocatalyzed asymmetric bromolactonization reaction of aryl acrylate-type carboxylic acids.

A new strategy based on the Catellanireactions has enabled the one-pot synthesis of ortho-iodobiaryls starting from aryl iodides and bromides. Beyond the synthetic utility of this transformation (32 examples and 6 subsequent derivatizations), a DFT study provides insights on the mechanism of the reductive elimination step, which is driven by an original transmetallation between palladium(II)-halide
