Abstract
General methods for the preparation of 3-substituted 5-aryl-1λ4,2,4-thiadiazine 1-oxides are described. The chemical properties of these new heterocyclic systems have been explored, for example their susceptibility to electrophilic and nucleophilic attack. The 3-bromomethyl derivative can undergo a base-catalysed ring expansion to a seven-membered thiadiazepine; some initial studies at generating fused bicyclic systems from these heterocyclic precursors are also reported.This publication has 13 references indexed in Scilit:
