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.

Three complementary biocatalytic routes were examined for the synthesis of the cyclopropyl amine (1R,2S)-2, which is a key building block for the anti-thrombotic agent ticagrelor 1. By employing either a ketoreductase, amidase or lipase biocatalyst, the k
NOVEL PROCESS FOR PREPARING PHENYLCYCLOPROPYLAMINE DERIVATIVES USING NOVEL INTERMEDIATES

Paragraph 0147, (2013/06/27)
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.
