METHOD FOR THE PRODUCTION OF AMINO CROTONYL COMPOUNDS

摘要

The invention relates to a process for preparing a compound of general formula (VII): (see formula VII) comprising the following synthesis steps: a) reacting a compound of general formula (V) (see formula V) in suitable solvents after corresponding activation with di-(C1-4-alkyl)-phosphonoacetic acid; and b) reacting the resulting compound of general formula (VI) (see formula VI) with an aldehyde of formula (see formula a) or a corresponding aldehyde equivalent using suitable organic or inorganic bases.
