Highly enantioselective alkylation of tert-butyl α-fluoro-β-keto esters can be effected by the use of N-spiro chiral quaternary ammonium salt as chiral phase-transfer catalyst, as a complementary approach to the asymmetric fluorination of α-alkyl-β-keto esters.
通过使用 N-螺手性季铵盐作为手性相转移催化剂,作为 α-烷基-β 不对称氟化的补充方法,可以实现叔丁基 α-氟-β-酮酯的高度对映选择性烷基化-酮酯。
