Descrição

The [4π+2π] cycloaddition of non-classical heterocyclic-fused-[c]thiazoles was explored allowing the synthesis of a range of new nitrogen-bridged bi-, tri- and tetracyclic heterocyclic compounds namely, pyrazolo[1,5-a]pyridines, thiazolo[2,3,4-cd]pyrrolizines and indolizines. For the first time, one non-classical pyrrolo[1,2-c]thiazole was isolated and its structure determined by X-ray crystallography.
