    摘要: The present invention discloses an aminothiol compound having a general formula I wherein R1-R5 are substitutable ligands. Such compounds can perform as superior catalysts in asymmetric addition reactions of organic zinc and aldehyde. According to the present invention, the compounds is needed only less than 0.02% of main reactants to obtain enantioselectivity higher than 99% enantiomeric excess, whereby the asymmetric reactions can become very economic.

    摘要: The present invention discloses an acylated derivative of an aminothiol compound having a general formula II wherein R1-R4 and R6 are substitutable ligands. Such compounds can perform as superior catalysts in asymmetric addition reactions of organic zinc and aldehyde. According to the present invention, only less than 0.02% of the acylated derivative is needed to obtain high enantioselectivity over 99% enantiomeric excess.

    摘要: The present invention discloses an aminothiol compound having a general formula I wherein R1-R5 are substitutable ligands. Such compound can perform as a superior catalyst in an asymmetric addition reaction of organic metal compounds and aldehyde. According to the present invention, the aminothiol compound is needed only less than 0.02% based on main reactants to obtain enantioselectivity higher than 98% enantiomeric excess, whereby the asymmetric reactions can become very economic.
