Abstract

Cyclopropanes are present in many biological and medicinal molecules, 1 and are synthetically useful intermediates. 2 The Simmons–Smith reaction is a very effective method to synthesize cyclopropanes from olefins (Scheme 1). 3 Since the initial report of the Simmons–Smith reaction, 4 lots of modifications have been reported. 5 A variety of strategies have also been developed to generate various zinc species, including XZnCH 2 X, 6a,b RZnCH 2 I or ...
