Total synthesis of vinigrol.


ABSTRACT: The longstanding challenge posed by the complex diterpene vinigrol has been answered for the first time. The notorious difficulty in synthesizing vinigrol stems from its unprecedented decahydro-1,5-butanonaphthalene ring system, eight contiguous stereocenters, and highly congested functionality. This Communication delineates a stereocontrolled 23-step route to vinigrol that is scalable (>5 g prepared of a late-stage intermediate), minimally reliant on protecting group chemistry, and facilitated by a number of unique and chemoselective transformations.
