Abstract
[reaction: see text] Readily accessible propynols with a 2-thioxyphenyl substituent selectively undergo 5-exo-iodocyclization followed by tandem rearrangement and elimination or substitution processes to give selective access to either 2-acyl- or 2-(1-iodoalkeny)-benzo[b]thiophene systems.
