Asymmetric reduction of α-oxoketoxime ethers with the reagents prepared in situ from trimethyl borate and chiral amino alcohols derived from either L-proline or α-pinene was investigated. Both cyclic and acyclic α-oxoketoxime ethers were reduced to afford the corresponding chiral 1,2-amino alcohols with high enantioselectivities.
研究了用由硼酸三甲酯和衍生自L-脯氨酸或α-chi烯的手性氨基醇原位制备的试剂对α-氧肟肟醚的不对称还原。环状和无环α-氧代肟醚都被还原,得到相应的具有高对映选择性的手性1,2-氨基醇。
