摘要

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–f, h, readily available from the condensation of 1-benzotriazolyl-3-chloroacetone 7 with aromatic or heteroaromatic thiols followed by dehydrative cyclization of 1-(benzotriazol-1-yl)-3-[aryl (hetaryl) thio] acetones 9d–f, h.
