Rhodium-catalyzed diastereoselective 1,2-addition of arylboronic acids to chiral trifluoroethyl imine
摘要:
Rhodium-catalyzed 1,2-addition of arylboronic acids 4a-j to chiral trifluoroethyl imine 3 afforded diastereomerically enriched sulfinamides 5a-j. The chiral auxiliary of the sulfinamide products was readily removed under acidic methanolysis to provide the corresponding trifluoroethylamine analogs 6a-j. (C) 2009 Elsevier Ltd.
