Abstract

Intramolecular cyclisation of simple allylic hydroperoxides to give substituted 1, 2— dioxolanes using electrophilic reagents has been investigated. Closure using mercury (II) acetate and electrophilic halogen reagents (NBS, Br2 ButOC1) occurs by Markovnikov— directed and conformationally strict stereospecificity. Subsequent free—radical reaction of the mercurated dioxolanes involved specific reaction involving reaction from the sterically ...
