enantioselectivity and the activity of the rhodium complex catalysts. Their rhodium complexes are much more effective than those of BPPM and (2S,4S)-N-(t-butoxycarbonyl)-4-(dicyclohexylphosphino)-2-[(diphenylphosphino)methyl]pyrrolidine (BCPM) for the asymmetric hydrogenation of dimethyl itaconate. The hydrogenation has also been used successfully in an efficient asymmetric synthesis of the key intermediate of new
我们制备了(2 S,4 S)-N-(叔丁氧羰基)-4-(二苯基膦基)-2-[((二苯基膦基)甲基]吡咯烷(BPPM)的类似物,带有对-二甲基氨基基团来证明关于膦基基团对铑配合物催化剂的对映选择性和活性的电子效应,我们的设计概念的实用性。它们的铑配合物比BPPM和(2 S,4 S)-N有效得多-(叔丁氧羰基)-4-(二环己基膦基)-2-[((二苯基膦基)甲基]吡咯烷(BCPM),用于衣康酸二甲酯的不对称氢化。氢化也已成功用于新型人肾素抑制剂关键中间体的有效不对称合成中。
