Abstract

Asymmetric fluorination of α-branched aldehydes catalyzed by chiral primary amines under mild conditions has been developed. Both enantiomers could be obtained with good yields (up to 96%) and a high enantioselectivity (up to 90% ee) by a simple swap of the fluorination reagents.

摘要

手性伯胺催化条件温和下α-支链醛的不对称氟化反应被开发出来。通过简单地改变氟化试剂,就能以高收率(高达 96%)和高对映选择性(高达 90%ee)得到两种对映异构体。
