Abstract
A multistep preparation is described for carboxyvinylsilane 6, which upon reaction with ozone initially gave dioxetane 8 as a transient intermediate in a highly stereoselective manner. Subsequent rearrangement at ambient temperature resulted in cyclization to (*)- hexahydroisochroman-3-one 2, whose relative stereochemistry was determined by X-ray crystallographic analysis and found to resemble the C, D-ring portion of the antimalarial ...
