Cu(OTf)2/trisoxazoline catalyzed asymmetric Friedel–Crafts reaction of pyrroles with alkylidene malonates
摘要:
In the presence of catalytic amount of Cu(OTf2/trisoxazoline, an enantioselective Friedel-Crafts reaction of N-methyl pyrrole with alkylidene malonates has been developed and LIP to 66% ee is achieved. (C) 2008 Elsevier Ltd. All rights reserved.
