Abstract
Novel solid-supported phosphonate reagents have been prepared and evaluated for the synthesis of alpha,beta-unsaturated esters with a preference for the Z-alkene. The optimal reagent was a hybrid of both Still-Gennari and Ando reagents, and showed good to high yields and fair to good Z-selectivity for the conversion of both aliphatic and aromatic aldehydes.
