| dc.description.abstract | Fragmentation of α-halosulfonyl cycloalkanol via radical were investigated. Three different reagents were employed i.e.: 1. α-Sulfonyl cyclobutyl carbinyl radicals could be generated by Tri-n -butyltin hydride (TBTH)/AIBN/benzene to give the fragmentation products and the radical formed by fragmentation could be trapped with acrylonitrile. 2. Alkoxy radicals could be generated by [bis(trifluoroacetoxy)iodo]benzene (BTFIB)/I(,2) or (diacetoxyiodo)benzene (DAIB)/I(,2) to give the fragmentation products or undergo intramolecular cyclization on olefinic side chains to give cyclic ethers. These reactions are useful synthetically for the preparation of highly functionalized acyclic intermediates and cyclic ether (Schemes A and B). | |
