Mm. Heravi et al., Solid acid induced heterocyclization under microwave irradiation. Highly selective synthesis of condensed thiazole, J CHEM R-S, (10), 2000, pp. 464-465
Condensed thiazoles are synthesized in satisfactory to good yields by the c
atalytic action of sulfuric acid adsorbed on silica gel under microwave irr
adiation in a solventless system.
