LETTERS TO THE EDITOR

The reaction of (E)-1,5-diarylpent-2-en-4-yn-1-ones with 2-mercaptobenzothiazole and 2-mercaptobenzimidazole occurs under the conditions of basic catalysis and leads to the formation of 2-{[(5-arylfuran-2-yl)phenylmethyl]sulfanyl}-1,3-benzazoles in 50–90% yields.

Keywords

conjugated enyne ketones furan derivatives 2-mercaptobenzazoles cyclization X-ray structural analysis
