Regioselective synthesis of 7-acetyl-11c-methyl-4b,5,7,11c-tetrahydro[1] benzofuro[2′,3′:4,5]thiopyrano[2,3-b]indoles by sequential Claisen rearrangement of 2-(4′-aryloxybut-2′-ynylthio)-1-acetylindoles

Hitherto unreported indole-annulated pentacyclic heterocycles containing oxygen, nitrogen and sulfur have been synthesised by thermal Claisen rearrangement followed by Lewis acid catalysed Claisen rearrangement. 9-Acetyl-4-aryloxymethyl-2,9-dihydrothiopyr
