A PROCESS FOR PREPARING 2-AMINOMALONIC ACID DERIVATIVES
摘要:
A process for producing 2-aminomalonic acid derivatives of general formula (1) (wherein A is linear or branched alkylene having 1 to 10 carbon atoms; R1 is linear or branched alkyl having 2 to 20 carbon atoms; R?2 and R3¿ may be the same or different and each represents lower alkyl or aralkyl; and R4 is a protective group) characterized by reducing compounds of general formula (6) (wherein A, R?1, R2, R3 and R4¿ are each as defined above.
