All the stereoisomers of stenusine (1) and norstenusine (21) have been efficiently synthesized by the asymmetric hydrogenation of pyridines. The (2R,3S)- and (2R,3R)-isomers of 1, that are difficult to prepare, have been synthesized for the first time using a chemoenzymatic approach in eight steps with an 8 % total yield. All the target compounds were obtained in good stereochemical purity by using
stenusine (1) 和norstenusine (21) 的所有立体异构体都已通过吡啶的不对称氢化有效合成。难以制备的 (2R,3S)- 和 (2R,3R)-异构体 1 已首次使用化学酶法分八步合成,总产率为 8%。通过使用非常简单和廉价的试剂和助剂,所有目标化合物均以良好的立体化学纯度获得。
