A chiral cagelike copper(I) catalyst for the highly enantioselective synthesis of 1,1-cyclopropane diesters
Deng, Chao,Wang, Li-Jia,Zhu, Jun,Tang, Yong
, p. 11620 - 11623 (2012)
Triangulation method: The catalytic enantioselective cyclopropanation of multisubstituted olefins with phenyliodonium ylide malonate has been achieved in the presence of a chiral bisoxazoline copper(I) complex (see scheme). A wide range of substrates undergo the reaction to provide optically active 1,1-cyclopropane diesters in high yield with up to >99 %-ee. A rationale for the enantioselective induction has been proposed. Copyright
