Abstract
The formal syntheses of N-methylwelwitindolinone C isothiocyanate (4) and several other welwitindolinones 5–8 were achieved by the independent synthesis of 79. The synthesis featured a Lewis acid-mediated coupling between a heteroaryl carbinol and bis-TMS enol ether, an intramolecular enolate arylation, and an unprecedented intramolecular allylic alkylation of a γ-acyloxyenone.
