The syntheses of the dimethylester of (-)-(1R)-cis-homocaronic acid (7 steps, overall yield 43 %) and its antipode, the dimethylester of (+)-(1S)-cis-homocaronic acid (5 steps, overall yield 27 %), were performed starting from (+)-3-carene and its derivatives, (+)-4α-acetyl-2-carene and (+)-4α-acetoxymethyl-2-carene. Oxidative cleavage in the key stages was carried out by ozonization.
