A direct preparation of silyl oxazoles: a dramatic chemoselectivity difference between R3SiOTf and R3SiCl
摘要:
General. highly selective silylation conditions for the ambident oxazole anion (isocyano enolate) have been found. The chemoselectivity between O-silylation and C-silylation changed from <1:99 to >99:1 upon switching from R3SiCl to R3SiOTf. (C) 2002 Elsevier Science Ltd. All rights reserved.
