Convenient One-pot Synthesis of Cyclopropyl Sulfones via Successive Alkylation and Cyclization of Sulfone-stabilized Carbanions

Tanaka, Kazuhiko,Suzuki, Hitomi

, p. 2071 - 2074 (2007/10/02)

A general one-pot approach to cyclopropyl sulfones has been demonstrated, which involves the alkylation of lithiomethyl phenyl sulfone with an epoxide followed by cyclization of the resulting carbanion.Alkylation of the dianion derived from 3-arylsulfonyl
