Abstract:

Chiral cyclic amino alcohols with contiguous stereocenters are key building blocks in the synthesis of bioactive molecules and pharmaceuticals. Artificial cascade biocatalysis represents an attractive method for the synthesis of chiral molecules bearing multiple stereocenters from readily available materials. Here we reported an artificial cascade biocatalysis comprising an epoxide hydrolase, an alcohol dehydrogenase, and a reductive aminase or an amine dehydrogenase. It can be utilized to access all four stereoisomers of 2-aminocyclohexanol with two contiguous stereocenters in high yields (up to 95%) and excellent stereoselectivity (up to 98% de) starting from readily available cyclohexene oxide without isolation of the intermediates. Additionally, the biocatalytic cascade has been successfully extended to the production of structurally diverse 2-(alkylamino)cyclohexanols by replacing ammonia with different organic amines.
