โœฆ Synopsis

On the biogenetic type synthesis of polycyclic terpenoid from acyclic precursor, there are several reports* in which the initiation of ring closure is caused by i.) protonation to the terminal Couble bond, or ii) opening of the

The functionalized tricyclic nagilactone precursor 19 was synthesized by a route featuring a vinylsilane terminated/1,3-dioxane acetal initiated bicyclization. Relative and absolute stereochemical control were achieved via the optically active pentenolide template 14.
