✦ Synopsis

Hitherto unreported 3-(aryloxyacetyl)-2,3-dihydrothieno[3,2-c][1] benzopyran-4-ones 5a-f were synthesised in 70-75% yields by the application of the sulfoxide rearrangement of 4-(4-aryloxybut-2-ynylthio)[1]benzopyran-2-ones 4a-f. The substrates 4a-f were synthesised by phase-transfer-catalysed alkylation of previously unreported 4-mercaptocoumarin.
