“…Topiramate azidosulfate was synthesized using a modification of procedures found in the literature (Maryanoff et al, 1987;Kankan et al, 2004;Arvai et al, 2006;Koruyucu et al, 2016). The synthesis involved three steps, viz., (1) synthesis of 2,3:4,5 bis-O-(1-methylethylidene)--d-fructopyranose, (2) synthesis of 2,3:4,5-bis-O-(1-methylethylidene)-1-chlorosulfate--dfructopyranose, and (3) synthesis of topiramate azidosulfate (I), as depicted in Fig.…”
