摘要

Abstract The synthesis of 3, 4-didehydroionone isomers 4,(+)-6, and (−)-6 and of 3, 4- didehydro-7, 8-dihydroionone isomers 5,(+)-7, and (−)-7 was accomplished starting from commercially available racemic α-ionone (1). Their preparation of the racemic forms 4–7 was first achieved by mean of a number of chemo-and regioselective reactions (Schemes 1 and 2). The enantio-and diastereoselective lipase-mediated kinetic acetylation of 4- ...
