Dimerization of Butenolide Structures. A Biomimetic Approach to the Dimeric Sesquiterpene Lactones (±)-Biatractylolide and (±)-Biepiasterolide
摘要:
The biomimetic synthesis of the bisesquiterpene lactones (+/-)-biatractylolide 1 and (+/-)-biepiasterolide 2 via dimerization of the captodative stabilized radical 8 is reported. Atractylon 7 has also been shown to be a possible intermediate during the biosynthesis of biatractylolide 1, biepiasterolide 2, atractylolide 3, and hydroxyatractylolide 4.

Total synthesis of seven bioactive atractylenolide-type eudesmanolides from Hagemann’s ester, following, a short, scalable, adaptable, and diversity oriented protocol, has been accomplished. This effort opens a gateway to access through synthesis an exceptionally potent and promising group of natural products and their congeners of contemporary interest.

A series of methyl hydronaphthyl alcohols, formates, acetates, and ketones were prepared and their odour properties evaluated. Minor structural changes, even opposite to the osmophoric group, were found to have major effects on the odour. 13CNMR shift assignments of the hydronaphthyl derivatives are presented.
