资源简介：
We report herein
an enantioselective cyclopropanation of β,γ-unsaturated
α-ketoesters with diazoesters by the complexes of InBr3 and chiral calcium phosphate. The reaction proceeds via a Michael
addition–cyclization pathway to afford highly functionalized
chiral cyclopropanes with excellent enantioselectivities (up to >99%
ee) as a single diastereoisomer.
