PHOSPHINIC ACID DERIVATIVES AND PROCESS FOR PREPARING THE SAME |
摘要 |
Disclosed is a novel process for preparing [(3-amino-3-carboxy)-propyl-1]phosphinic acid derivatives, comprising reacting an alkylalkylphosphonyl halide with a vinylmagnesium halide to form a vinylphosphinic acid derivative, and reacting the vinylphosphinic acid derivative with a Shiff's base to form the aimed product. Also disclosed is a novel intermediate compound formed during the course of the above process, which compound has the general formula: <IMAGE> (wherein R1, R2, R3, R4 and R5 are as defined in the specification). |
