Resumo

Stereospecific 1-alken-1-ylboronates readily react with in situ generated chloromethyllithium, producing the corresponding allylboronate in good yields and in excellent stereochemical purities. These are very important synthetic intermediates and conversion of a representative derivative, [E]-2-(2-heptenyl)-1,3,2-dioxaborinane, 2 (R1 = C4H9, R2 = R3 = H), into several compounds of synthetic interest is described.
