, (2020/05/26)
The present invention provides a new, scalable synthetic method for the preparation of non-racemic 1-cyclopropyl alkyl-1-amines, e.g. (S)- 1-cyclopropyl ethyl-1-amine. The method makes use of inexpensive starting materials (such as cyclopropyl methyl keto

Asymmetric reductive amination of ketones using ω-transaminases (ω-TAs) offers a promising alternative to the chemocatalytic synthesis of chiral amines. One fundamental challenge to the biocatalytic strategy is the very low enzyme activities for most ketones compared with native substrates (i.e., cat/KM for acetophenone). The W58L mutant afforded an efficient synthesis of enantiopure amines (i.e., >99% ee) using isopropylamine as an amino donor.
