Title:
METHOD FOR BIOLOGICALLY PREPARING (1R,2S)-2-(3,4-DIFLUOROPHENYL)CYCLOPROPANAMINE D-MANDELATE (I)
Document Type and Number:
WIPO Patent Application WO/2018/090929
Kind Code:
A1
Abstract:
Provided is a method for biologically preparing (1R,2S)-2-(3,4-difluorophenyl)cyclopropanamine D-mandelate (I), comprising: (a) performing an asymmetric reduction reaction with a compound of formula (VI) as a substrate in the presence of a coenzyme under the catalysis of a carbonyl reductase in a liquid reaction system, so as to form a compound of formula (V); (b) reacting the compound of formula (V) with triethyl phosphonoacetate to obtain a compound of formula (IV); and (c) subjecting the compound of formula (IV) to ammonolysis and Hofmann degradation, and then salt formation with D-mandelic acid to obtain a compound of formula (I). The reaction system comprises: (i) an aqueous solvent; (ii) a substrate, which is a compound of formula (VI); (iii) a coenzyme; (iv) a carbonyl reductase; (v) a cosubstrate; and (vi) an enzyme for the regeneration of the coenzyme.
