Abstract :
The 1,4-dipole derived from 4,5-dimethylthiazole and DMAD has been shown to react readily with chromone-3-carboxaldehydes resulting, after an unusual rearrangement, in the facile synthesis of thiazolo[3,2-a]pyridine derivatives; in some instances tetracyclic chromenothiazolopyridines were formed.
