Abstract
Base-assisted cyclizations of 1-[3-[hydroxy(substituted methyl)]propar gyl]benzotriazoles, derived from lithiated 1-propargylbenzotriazole (1 ) and aromatic aldehydes or ketones, gave 2-arylfurans 5 or 1-(5,5-dia ryl-2,5-dihydrofuran-2-yl)benzotriazoles 7, respectively, in high yiel ds. Compounds 7 with Grignard reagents yielded trisubstituted 2,5-dihy drofurans 9.
