-
Page/Page column 46-47, (2012/10/18)
A process for preparation of cycloalkanedicarboxylic acid monoesters which is characterized by comprising: a first step of protecting two carboxyl groups (-COOH) of a compound represented by formula (1-A) with a group represented by Z to obtain a compound represented by formula (2-A), and a second step of deprotecting either of the groups represented by Z of the compound represented by formula (2-A) obtained in the first step with an acid to obtain a compound represented by formula (3-A). wherein m represents an integer of 0 to 3, p represents 0 or 1, Z represents a methylsulfanylmethyl group etc., and R5, R6 and R7 each independently represent a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, a phenyl group or a benzyl group.
