Abstract

3,7-Dimethyl-7-hydroxy-2-octen-1,6-olide and 3,7-dimethyl-2,6-octadien-1,6-olide, the natural bioactive compounds isolated from the fruit of Litsea cubeba and the liverwort Plagiochila rutilans, were totally synthesized using easily available cis-geraniol as raw material in short, convenient, and low-cost, five-step reactions including three steps of oxidation, cyclization, and dehydration, with an overall yield of 47.5% and 37.3%.
