2,3-二氢[1,3]噻唑并[3,2-a]苯并咪唑-3-醇 | 2,3-dihydro-benzo[4,5]imidazo[2,1-b]thiazol-3-ol | 16458-64-3 | C9H8N2OS | 192.241 |
Thiazolo[3·2-a]benzimidazole (I) and several of its derivatives were synthesized by annelation of the thiazole ring to a benzimidazole. The intermediate 3-hydroxy-2,3-dihydrothiazolo[3·2-a] benzimidazoles were identified and the 3-position of the hydroxyl group was established by oxidation to 3-(2H)-thiazolo[3·2-a]benzimidazolone. Tautomerism of the 3-hydroxy-2,3-dihydrothiazolo[3·2-a]benzimidazoles was also investigated.3-Hydroxy-2,3-dihydrothiazolo[3·2-a]benzimidazole and the corresponding 3-methyl compound were found to undergo nitrogen acetylation and rearrangement under acetylating conditions.
