Document Type and Number:
Japanese Patent JP2008540464
Kind Code:
A
Abstract:
Carbonyl compounds of the formula (II), wherein R1 and R2 are as defined herein, react in the presence of an amine with carboxylic acid derivatives of the formula (II), wherein R3 and EWG are also as defined herein, to give alpha,beta-unsaturated compounds of the formula (I) according to the following scheme: It is possible under mild reaction conditions to obtain unsaturated esters with high (E) stereoselectivity. The reaction typically proceeds at room temperature or lower without particular requirements such as inert gas, exclusion of moisture, heat, etc., being made. The only by-products obtained are CO2 and water.
