A stereoselective debromoborylation of aliphatic 1,1-dibromo-1-alkenes to prepare (Z)-1-bromo-1-alkenylboronate esters using copper(i) catalysts was developed. The debromoborylation of various aliphatic 1,1-dibromo-1-alkenes in the presence of a copper(i) catalyst and bis(pinacolato)diboron proceeded smoothly to produce (Z)-1-bromo-1-alkenylboronate esters in good yields with only Z geometry.

A stereocontrolled synthesis of the dihydroxyethylene dipeptide isostere, A-82768, 1 via an erythro-selective addition of a Grignard reagent to a cis α,β-epoxy aldehyde is described. The resulting erythro-epoxy alcohol was converted to the desired 3-amino
Use of lithium (trimethylstannyl)(cyano)cuprate for the conversion of alkyl 2-alkynoates into alkyl (Z)- and (E)-3-trimethylstannyl-2-alkenoates

Reaction of functionalized alkyl 2-alkynoates (e.g., 13-19) with lithium (trimethylstannyl)(cyano)cuprate (3) under two sets of carefully defined experimental conditions provides, efficiently and stereoselectively, either alkyl (Z)- or (E)-3-trimethylstan
