, (2019/11/29)
The invention relates to a synthetic method for an arylcyclopropylamine compound. The method comprises the following steps: with a cinnamaldehyde compound as a raw material, reacting the cinnamaldehyde compound with bis(pinacolato)diboron to obtain a boroalkylated product; and then subjecting the boroalkylated product and an aminated compound to a ring-closure reaction so as to obtain the arylcyclopropylamine compound. Compared with the prior art, the invention has the following advantages: the synthetic method of the invention is simple to operate and short in reaction time; reagents used inthe invention are cheap and easily available; the target arylcyclopropylamine compound can be prepared from most substrates at a high overall yield and is mainly in the form of transconfiguration; anda route of the method is obviously improved, more economical, safer and easy for industrial production.

Engineered hemoproteins have recently emerged as promising systems for promoting asymmetric cyclopropanations, but variants featuring predictable, complementary stereoselectivity in these reactions have remained elusive. In this study, a rationally driven strategy was implemented and applied to engineer myoglobin variants capable of providing access to 1-carboxy-2-aryl-cyclopropanes with high trans-(1R,2R) selectivity and catalytic activity. The stereoselectivity of these cyclopropanation biocatalysts complements that of trans-(1S,2S)-selective variants developed here and previously. In combination with whole-cell biotransformations, these stereocomplementary biocatalysts enabled the multigram synthesis of the chiral cyclopropane core of four drugs (Tranylcypromine, Tasimelteon, Ticagrelor, and a TRPV1 inhibitor) in high yield and with excellent diastereo- and enantioselectivity (98–99.9% de; 96–99.9% ee). These biocatalytic strategies outperform currently available methods to produce these drugs.
