A totalsynthesis of (+)-taxusin (1) has been realized by virtue of the development of a practical route for complete functionalization of the A ring. To achieve this goal, it proved necessary to devise a strategy that would enable chemical transformations to proceed in a very congested environment. The successful pathway from 2 required 19 steps consisting principally of chemoselective oxidation and
