2-(Benzotriazol-1-ylmethyl)furans 4a-c, on treatment with n-BuLi followed by various α,β-unsaturated ketones and aldehydes, gave the adducts 6a-f which underwent intramolecular cyclization to form substituted benzo[b]furans 10a-f. Lithiation and subsequen

4-Substituted and 4,5-disubstituted 2-(benzotriazol-1-ylmethyl)furans 3 have been prepared in good yields from 1-propargylbenzotriazole (1) and α-bromo ketones via one-pot processes. The 2-(benzotriazol-1-ylmethyl) side chain of 3 was alkylated by lithiat
