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 key building blocks for synthesis of the amine 2 were obtained in 99.9, 92.5 and 46.3 ee, respectively.
研究了三种互补的生物催化途径,以合成环丙胺(1 R,2 S)-2,这是抗血栓形成剂替卡格雷1的关键组成部分。通过使用酮还原酶,酰胺酶或脂肪酶生物催化剂,分别在99.9、92.5和46.3 ee中获得了合成胺2的关键结构单元。
