eurjchem-411	Gaber, Hatem Moustafa; Bagley, Mark Christopher	Regioselective synthesis and biological evaluation of some novel thiophene-containing heterocyclic scaffolds as potential chemotherapeutic agents	2011	9	.pdf	application/pdf	8026	459	60	Since compound 4 contains two adjacent reactive functional groups, it reacted readily with different electrophilic reagents to provide a series of thieno[2,3‐ d]pyrimidin‐4‐one derivatives with annelated bridgehead nitrogen heterocycles 8‐11, whereas a second series of 3‐heteroaryl‐substituted thiophenes 13‐17 was obtained by thioamide functionalization in 1,3,4‐oxadiazole derivative 5 using various chemical reagents. Compounds 1 [18‐22] and 2a [23] were prepared according to known methods (Scheme 1).	cache/eurjchem-411.pdf	txt/eurjchem-411.txt
