Abstract

original image

Takemoto promotes: Enantiomerically pure bifunctional chiral catalysts are immobilized on poly(methylhydrosiloxane). A supported Takemoto-type catalyst promoted the diethyl malonate addition to nitrostyrene in fair to good yields and up to 83 % ee, and its recyclability is demonstrated.
