Abstract

A process for preparing 2 -methylene- 3-(4-methylcyclohex-3-enyl)- butanal or 2-methylene-3-(4-methylcyclohexyl)- butanal comprises reacting 3-(4-methylcyclohex-3-enyl)-butanal or 3-(4-methylcyclohexyl)-butanal with formaldehyde or a formaldehyde- forming compound and in the presence of a catalytic amount of a secondary amine. The 3-(4-methylcyclohex-3-enyl)- butanal or 3-(4-methylcyclohexyl)- butanal may be prepared from limonene. 2-methylene-3-(4-methylcyclohex- 3-enyl)-butanal and 2-methylene-3- (4-methylcyclohexyl)-butanal are fragrant novel compounds.
