Article abstract of DOI:10.1021/jo00063a022

Base-assisted cyclizations of 1-<3-propargyl>benzotriazoles, derived from lithiated 1-propargylbenzotriazole (1) and aromatic aldehydes or ketones, gave 2-arylfurans 5 or 1-(5,5-diaryl-2,5-dihydrofuran-2-yl)benzotriazoles 7, respectively, in high yields.Compounds 7 with Grignard reagents yielded trisubstituted 2,5-dihydrofurans 9.
