Preparation and synthetic utility of 3-(benzotriazol-1-ylmethyl)areno- and -hetareno[b]thiophenes

3-(Functionalized-methyl)- and 3-alkenylareno(hetareno)[b]thiophenes 13-16 are prepared via the side chain elaboration of 3-(benzotriazol-1-ylmethyl)thiophenes 10d-fh, readily available from the condensation of 1-benzotriazolyl-3-chloroacetone 7 with aromatic or heteroaromatic thiols followed by deh...

Summary:3-(Functionalized-methyl)- and 3-alkenylareno(hetareno)[b]thiophenes 13-16 are prepared via the side chain elaboration of 3-(benzotriazol-1-ylmethyl)thiophenes 10d-fh, readily available from the condensation of 1-benzotriazolyl-3-chloroacetone 7 with aromatic or heteroaromatic thiols followed by dehydrative cyclization of 4-(benzotriazol-1-yl)-3-[aryl(hetaryl)thio]acetones 9d-fh.
