Solid-phase preparation of amides using N-acylbenzotriazoles

Alan R. Katritzky; Boris V. Rogovoy; Nataliya Kirichenko; Vladimir Y. Vvedensky

Wang resin linked amines were efficiently converted into amides using acylbenzotriazoles. Cleavage of resins gave the desired amides 7Aa-Gf in 30-99% yields with good to excellent purities.

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

Alan R. Katritzky; Vladimir Y. Vvedensky; Dmytro O. Tymoshenko

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.
