Abstract: A new strategy for the synthesis of benzothiophenes through formal [3+2] annulation of sulfanylacetaldehyde and cyclohexa-2,4-dien-1-one monoketals has been developed. This approach relies on the ease of aromatization of tetrahydrobenzothiophenone derivatives prepared by the aforementioned… read more here.
