-
Paragraph 0006; 0010, (2017/10/12)
The invention discloses a synthesis method of a levo-amino compound S-7-chloro-1,2,3,4-tetrahydronaphthalene-1-amine. The method includes the steps of: performing a reaction to a raw material, 7-chloro-1-tetralone, with hydroxylamine to generate oxime; performing hydrogenation reduction to the oxime to prepare racemized amine; performing a one-pot dynamic kinetic resolution reaction to the product amine with lipase, a racemization catalyst and an acyl group donor; and hydrolyzing a resolution reaction product to prepare the S-7-chloro-1,2,3,4-tetrahydronaphthalene-1-amine. The method has simple operations, high product yield, high optical purity of the resolution product, and the like.
