Abstract:
A process of producing a 1,1-cyclohexanedimethanol compound having a substituent group at least at the 2-position thereof of formula (1): (wherein R and R1 to R6have the same meanings below), comprising the steps of:reacting a &bgr;-substituted-&agr;,&bgr;-unsaturated aldehyde of formula (2): Râ€”CH&boxH;CHâ€”CHOâ€ƒâ€ƒ(2) (wherein R represents an alkyl group having 1 to 4 carbon atoms or a phenyl group) and a chain conjugated diene compound of formula (3): (wherein R1 to R6 independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms) in the presence of an anhydrous tin (IV) halide catalyst to obtain a 3-cyclohexene-1-carbaldehyde having a substituent group at least at the 6-position thereof of formula (4): (wherein R and R1 to R6have the same meanings as defined above),â€ƒreacting the compound of formula (4) with formaldehyde in the presence of an alkali catalyst to obtain a 1-hydroxymethyl-3-cyclohexene-1-carbaldehyde compound having a substituent group at least at the 6-position thereof of formula (5): (wherein R and R1 to R6 have the same meanings as defined above), andâ€ƒsubjecting the compound of formula (5) to hydrogenation reaction.
