An efficient 1,7-asymmetric induction was achieved with up to 82% diastereoisomeric excess (d.e.) in the diastereoselective reduction of the γ-keto ester 4 and o-acetylbenzoate 6 using the chiral podand 2 as chiral auxiliary.
使用手性豆荚2作为手性助剂,可实现高达82%的非对映异构体过量(de)的高效1,7-不对称诱导,其中γ-酮酸酯4和邻乙酰基苯甲酸酯6的非对映选择性还原。
