Chelation controlled diastereofacial selectivity in crotyltri--butylstannane additions to α-alkoxyaldehydes
摘要:
Lewis acid mediated additions of crotyltri-n-butylstannane to chiral α-alkoxyaldehydes generally show excellent (99:1) diastereofacial selectivity; proper choice of lewis acid is crucial for controlling erythro/threo selectivity in the bond formation.
