Bicyclic triazoles. 1. 3-(2-Furyl)-5-phenylthiazolo-[2,3-c]-s-triazole

Eco-friendly synthesis of 1-Aryl-8-methoxythiazolo [2’, 3’ : 3, 4] [1, 2, 4] triazino [5, 6-b] indoles under microwave ir-radiations

“…Infrared spectra (n max in cm -1 ) were recorded in nujol mull or KBr on a Perkin-Elmer 842/Beckman IR-20 / Hitachi 215 spectrometers. The proton magnetic resonance spectra were recorded on a VXR-200 MHz or R-32 Perkin-Elmer 90 MHz spectrometer in CDC1 3 or DMSO-d 6 using tetramethylsilane (TMS) as internal reference stadnard. The chemical shifts are expressed in (ppm) units downfield from TMS.…”

“…The results are shown in Table- We further explore our work by irradiated 6-Methoxyisatin-3-(4-p-chloropheny1-2-thiazoly1) hydrazone hydrobromide (IIa; Ar = p-C1C 6 …”

“…containing thiazole and related heterocycles (thiadiazole and thiadiazine) exhibit antihistaminic, antithyroid, antitubercular, antifungal & antibacterial activities [1][2][3] and their synthetic importance has been greatly enhanced by the recent uses of their condensed bridgehead nitrogen heterocycles as anthelminitics, antidepressants, platelet aggregation inhibitors, antineoplastic, vulcanization accelerators and photographic sensitizers [4][5][6][7][8][9][10][11] . The indoles are already been synthesized by different method But they requires longer reaction time and tedious workup [12][13][14][15][16][17][18][19][20][21] .…”
