Bis-aza-Wittig reactions of ethyl 4-[(triphenylphosphanylidene)amino]-2,3-dihydro-3-phenyl-2-thioxothiazole-5-carboxylate (iminophosphorane 1) with aromatic diisocyanate and nucleophilic reagents produced novel benzene-bridged bis(thiazolo[4,5-d]pyrimidin-7(6H)-one) derivatives in the presence of EtONa in 56%~92% yields. The structures of compounds were confirmed by 1H NMR, IR, MS and elemental analysis.

Key words: benzene-bridged, thiazolo[4,5-d]pyrimidin-7(6H)-one, multicomponent reaction, iminophosphorane
