摘要:
Functionalised mixed alkyl(trimethylsilylmethyl)zinc reagents add efficiently to a wide variety of Michael accepters in high yield and with exclusive 1,4-regioselectivity, without the need for transition metal catalysis. The trimethylsilylmethyl group behaves as a nontransferable group, and in no cases was transfer of this group observed. (C) 1998 Elsevier Science Ltd. All rights reserved.
