ORGANIC SYNTHESIS USING HALOBORATION REACTION XVIII. A STEREOSELECTIVE SYNTHESIS OF β-MONO- AND β,β-DISUBSTITUTED α,β-UNSATURATED ESTERS

Article abstract of DOI:10.1016/S0040-4039(01)89020-1

β-Mono- and β,β-disubstituted α,β-unsaturated esters can be prepared in good yields stereoselectively by the stepwise alkylation and alkoxycarbonylation of 2-bromo-1-alkenylboronates.
