Abstract

The synthesis of saturated bis-spiroacetal (11) from an intramolecular catalysed cyclization of a keto-epoxide together with the preparation of unsaturated bis-spiroacetal (16) via a Barton-type reaction of substituted hydroxy spiroacetal (15) highlight a means of constructing the above-named ring system.
