Title:
触媒、及び反応方法
Document Type and Number:
Japanese Patent JP5299974
Kind Code:
B2
Abstract:
Disclosed is a technology for enabling an efficient asymmetric Michael addition reaction which does not require a large amount of a malonic ester, while having a short reaction time. Specifically disclosed is a catalyst which is composed of MX 2 (wherein M is Be, Mg, Ca, Sr, Ba or Ra and X is an arbitrary group) and a compound represented by general formula [I]. [In the formula, R 7 , R 8 , R 9 and R 10 each represents a substituted cyclic group or an unsubstituted cyclic group.]
