The complexes of pyrrolidine bisphosphine ligands (CPMs) with rhodium (I) were found to be efficient catalysts for asymmetric hydrogenation of α-amino ketone hydrochloride derivatives. Utilizing this methodology, we have developed efficient asymmetric syntheses of the optically active β-amino alcohols, phenylephrine, levamisole, carnitine and propranolol.
吡咯烷双膦配体(CPMs)与铑(I)形成的复合物被发现是α-氨基酮 hydrochloride 衍生物的不对称加氢反应的高效催化剂。利用这一方法,我们开发了光学活性的β-氨基醇、苯肾上腺素、左旋咪唑、肉碱和普萘洛尔的高效不对称合成。
