High 1,4-syn-induction in the addition of chiral allyltrichlorostannanes to chiral aldehydes

Abstract

Chiral and achiral allyltrichlorostannanes reacted with chiral aldehydes to give the corresponding homoallylic alcohols with good to high diastereoselectivities. This approach has been applied to the synthesis of hydroxyethylene dipeptide isosteres L-682, 679, L-684,414, L-685,434 and L-685,458.1024026
