The present invention relates to compounds, particularly but not exclusively, compounds for use as catalysts, methods for producing said compounds and the use of said compounds as catalysts in catalytic processes including, but not limited to, the asymmetric reduction of imine and enamine compounds and/or the reductive amination of ketone compounds. The compounds have the formula 1 wherein: R1, R2, R3, R4 and R5 are each separately selected from the group consisting of hydrogen, alkyl and aryl; X is oxygen or sulfur; W is selected from the group consisting of – OR18,–SR18, –NR19R20, –PR19R20 where R18 is alkyl or aryl, and R19 and R20 are each separately selected from the group consisting of hydrogen, alkyl and aryl; and Z has the formula 2 wherein: R6 and R7 are each separately selected from the group consisting of hydrogen, alkoxy, nitro, halogen, alkyl and aryl, or R6 and R7 are linked to form a cyclic group; and Y is oxygen, sulfur or NR10 in which R10 is selected from the group consisting of hydrogen, alkyl and aryl.
本发明涉及化合物,特别是但不限于用作催化剂的化合物,生产上述化合物的方法以及将上述化合物用作催化剂在催化过程中的使用,包括但不限于对亚胺和烯胺化合物的不对称还原和/或对酮化合物的还原胺化反应。这些化合物的化学式为1,其中:R1、R2、R3、R4和R5分别从氢、烷基和芳基组成的群体中独立选择;X为氧或硫;W从-OR18、-SR18、-NR19R20、-PR19R20组成的群体中选择,其中R18为烷基或芳基,R19和R20分别从氢、烷基和芳基组成的群体中独立选择;Z的化学式为2,其中:R6和R7分别从氢、烷氧基、硝基、卤素、烷基和芳基组成的群体中独立选择,或者R6和R7连接形成一个环状基团;Y为氧、硫或NR10,其中R10从氢、烷基和芳基组成的群体中选择。
