N-(Methylcarbamoyl)-4-(dicyclohexylphosphino)-2-[(diphenylphosphino)methyl]pyrrolidine (MCCPM)- and N-(tert-butoxycarbonyl)-4-(dicyclohexylphosphino)-2-[(diphenylphosphino)methyl]pyrrolidine (BCPM)-rhodium(I) complexes werer efficient catalysts for asymmetric hydrogenations of β- and γ-amino ketone hydrochloride derivatives. Utilizing this methodology, we have developed efficient syntheses of fluoxetine and eprozinol from intermediate optically active amino alcohols.

The present invention relates to a cosmetic process for treating wrinkled skin, by topical application to the skin of a composition containing, in a physiologically acceptable medium, at least one secondary or tertiary carbonyl amine of formula (I):
1
The invention also relates to a novel family of carbonyl amines, and also to compositions containing them.
A new catalytic system has been developed for the asymmetrichydrogenation of β‐secondary‐aminoketones using a highly efficient P‐chiral bisphosphine–rhodium complex in combination with ZnCl2 as the activator of the catalyst. The chiral γ‐secondary‐amino alcohols were obtained in 90–94 % yields, 90–99 % enantioselectivities, and with high turnover numbers (up to 2000 S/C; S/C=substrate/catalyst ratio)
已经开发了一种新的催化系统,该系统使用高效的P-手性双膦-铑配合物与ZnCl 2作为催化剂的活化剂,对β-仲氨基酮进行不对称加氢。手性γ-仲氨基醇的产率为90-94%,对映选择性为90-99%,并且具有很高的周转率(最高2000 S / C; S / C =底物/催化剂比)。在NMR光谱和HRMS研究的基础上,已经提出了ZnCl 2对催化体系的促进作用的机理。该方法已成功应用于三种重要药物(S)-度洛西汀,(R)-氟西汀和(R)-atomoxetine,高收率且具有出色的对映选择性。
