作者:A. Srikrishna、R. Viswajanani、J.A. Sattigeri
DOI:10.1016/s0957-4166(03)00535-4
日期:2003.10
A four-step cyclopentenone annulation reaction of allylic alcohols employing a 5-exo-trig radical cyclisation reaction of mixed allyl methyl ketals of bromoacetone as the key step is described. The annulated product 1215 obtained from 2.3-dimethylcyclohexenol has been further elaborated into (+/-)-epibakkenolides employing a 5-exo-dig radical cylisation reaction based alpha-spiro-beta-methvlene-gamma-butyrolactone annulation methodology.
