Novel 3 Plus 2 annulation reaction of nitrones with Burgess reagent and a few related reactions

Abstract

Burgess reagent first prepared by E M Burgess in 1968 is a mild newlineand selective dehydrating agent for secondary and tertiary alcohols and newlinedue to the amphipolar nature it is gainfully employed in a number of newlinecreative synthetic ventures A close examination of the structure of newlineBurgess reagent reveals that it can act as a 1 2 dipole To the best of our newlineknowledge no attempts have been made to tap full synthetic potential of newlinethe amphipolar nature of this reagent and no reports on 1 3 dipolar newlineaddition to a and#963; bond in acyclic systems are available in literature In this newlinecontext we propose to unravel novel applications of Burgess reagent newlinebased on its amphipolar nature newline newline
