An external chiral ligand controlled enantioselective opening of oxirane and oxetane by organolithiums
摘要:
Enantioselective nucleophilic opening reactions of cyclohexene oxide and 3-phenyloxetane were achieved by the combination of an external chiral ligand and organolithiums in the presence of boron trifluoride to give the corresponding alcohols in up to 47% ee. (C) 1997 Elsevier Science Ltd.
