A versatile approach to the synthesis of highly functionalised carbocycles

Article abstract of DOI:10.1016/S0040-4039(99)00911-9

A synthetic route towards conduramine and carbasugar derivatives based on the transformation (i.e. two-carbon Wittig olefination and ester reduction) of the Vasella rearrangement product derived from D-galactose followed by either a [3,3] Overman or a [2,3]-Wittig-Still sigmatropic rearrangement, and subsequent ring-closing metathesis, is presented.
