An Unusual Enantioselective Aldol-Type Reaction of an Acetate Boryl Enolate Derived from a Chiral Thioimide
摘要:
The camphor-derived N-acetyloxazolidinethione has been used to effect enantioselective aldol type reactions of the derived 9-BBN enolate with a variety of aldehydes. Mechanistically, the observed facial selectivity is best explained by a boatlike transition structure.
