First syntheses of 1,13- and 1,15-dihydroxyherbertenes, and herbertenolide by applying intramolecular Heck reaction for the construction of adjacent quaternary centers
摘要:
1,13- and 1,15-Dihydroxyherbertenes and hebertenolide, typical herbertane-type sesquiterpenes with an oxidized methyl group, were synthesized by using intramolecular Heck reaction for the construction of adjacent quaternary centers. (C) 2001 Elsevier Science Ltd. All rights reserved.
