The firsttotalsynthesis of the tremorgic mycotoxin furnitremorgin C (1a) employing 6-methoxy-N-hydroxytryptophan (5a) is presented. Our approach features formation of the nitrone (6a), stereoselective cycloaddition to yield 7a, ring opening and coupling with an L-proline derivative to form 14. Base-catalysed epimerisation gave 16, which was converted into the title compound by deprotection of the
