- Palladium-Catalyzed Direct C-H Carbonylation of Free Primary Benzylamines: A Synthesis of Benzolactams
-
A protocol for palladium-catalyzed C-H carbonylation of readily available free primary benzylamines using NH2 as the chelating group under an atmospheric pressure of CO has been achieved, providing a general, atom- and step-economic approach to

- Traceless Directing Group Assisted Cobalt-Catalyzed C?H Carbonylation of Benzylamines
-
The first example of cobalt-catalyzed C(sp2)?H carbonylation of benzylamines using a traceless directing group is reported, which was successfully applied to the synthesis of N?unprotected iso-indolinones through direct C?H/N?H bonds activation. This protocol tolerates a variety of functional groups and provides a facile and efficient method for the formal synthesis of (+)-garenoxacin. (Figure presented.).

- Convenient access to isoindolinones via carbamoyl radical cyclization. Synthesis of cichorine and 4-hydroxyisoindolin-1-one natural products
-
An efficient and convenient access to 2-tert-butylisoindolin-1-ones via an oxidative radical cyclization process from stable carbamoylxanthates, derived from secondary tert-butylamines, is described. The proposed mechanism for this transformation involves, the generation of a carbamoyl radical, its cyclization to the aromatic system, and the dilauroyl peroxide (DLP) mediated rearomatization to generate the isoindolinone ring system. Additionally, the syntheses of cichorine and 4-hydroxyisoindolin-1-one natural products were carried out to underscore the synthetic potential of this xanthate-based carbamoyl radical-oxidative cyclization.

- Carbamoyl radicals from carbamoylxanthates: a facile entry into isoindolin-1-ones
-
It has been found that carbamoylxanthates derived from secondary t-butyl amines are stable compounds which function as efficient sources of carbamoyl radicals. The carbamoylxanthates derived from t-butylbenzylamines can be efficiently transformed into 2-t

- Stereoselective synthesis of a potent thrombin inhibitor by a novel P2-P3 lactone ring opening
-
The concise synthesis of a potent thrombin inhibitor was accomplished by a mild lactone aminolysis between an orthogonally protected bis-benzylic amine and a diastereomerically pure lactone. The lactone was synthesized by the condensation of L-proline met
