A copper-catalyzed asymmetric hydrosilylation of β-nitroethyl aryl ketones has been disclosed, and the corresponding chiral alcohols could be obtained in high yields (up to 99% yield) and excellent enantioselectivities (up to 96% ee). Moreover, the reaction worked well on a gram scale with 0.3 mol % of ligand loading, indicating that our protocol has potential applications in the synthesis of important pharmaceuticals such as Tranylcypromine and Ticagrelor.

Provided herein is a novel process for the preparation of phenylcyclopropylamine derivatives, which are useful intermediates in the preparation of triazolo[4,5-d]pyrimidine compounds. Provided particularly herein is a novel, commercially viable and industrially advantageous process for the preparation of a substantially pure ticagrelor intermediate, trans-(1R,2S)-2-(3,4-difluorophenyl)-cyclopropylamine. The intermediate is useful for preparing ticagrelor, or a pharmaceutically acceptable salt thereof, in high yield and purity.
