Rh-catalyzed intramolecular debenzylative cyclization of amines. Butyrolactams from benzylamines having a chloroacetylene moiety
摘要:
When benzylamines having a chloroacetylene moiety were heated in wet toluene with a catalytic amount of rhodium trifluoroacetate dimer, intramolecular debenzylative cyclization took place to give butyrolactams. This method is a new entry to selective debenzylation of amines. (C) 2011 Elsevier Ltd. All rights reserved.
