CARBOXYLIC ESTERS AND ALDEHYDES OF OMEGA,OMEGA-DIACYLOXY-2,6-DIMETHYL OCTATRIENE, PROCESS FOR THEIR PREPARATION AND THEIR USE IN THE SYNTHESIS OF TERPENE COMPOUNDS

摘要

omega , omega -Diacyloxy-2,6-dimethyl-octatrienoates and -octatrienals, as novel bifunctional asymmetric C10 building blocks for terpene syntheses, which possess a formyl or alkoxycarbonyl group at one chain end and 2 geminal acyloxy groups at the other, and a process for their preparation from readily obtainable industrial C5 building blocks and their use for the synthesis of terpene compounds by carbonyl olefination under conventional conditions.
