英文摘要	Efficient cyclopropanation of alpha,beta-unsaturated ketones using alpha-ketoesters or isatin derivatives is reported. The cyclopropanation reaction occurs via a cascade transformation that starts with addition of deprotonated dialkyl phosphite to the keto groups of alpha-ketoesters or isatin derivatives, followed by [1,2]-phosphonate/phosphate rearrangement to generate alpha-phosphonyloxyenolate intermediates, which are trapped by alpha,beta-unsaturated ketones via Michael addition/ring closure. This protocol was used to synthesize tetra-substituted cyclopropanes with a 1,2-cis-1,3-trans configuration in high yield with excellent diastereos electivity.
