Tandem Rh(III)-Catalyzed Oxidative Acylation of Secondary Benzamides with Aldehydes and Intramolecular Cyclization: The Direct Synthesis of 3-Hydroxyisoindolin-1-ones
摘要:
The rhodium-catalyzed oxidative acylation. between secondary benzamides and aryl aldehydes via sp(2) C-H bond activation followed by an intramolecular cyclization is described. This method results in the direct and efficient synthesis of 3-hydroxyisoindolin-1-one building blocks.

The rhodium(III)-catalyzed olefination of various carboxamides with alpha-CF3-substituted allylic carbonate is described. This reaction provides direct access to linear CF3-allyl frameworks with complete trans-selectivity. In particular, a rhodium catalyst provided Heck-type gamma-CF3-allylation products via the beta-O-elimination of rhodacycle intermediate and subsequent olefin migration process.
