Studies on the Synthesis of Stemona Alkaloids; Stereoselective Preparation of the Hydroindole Ring System by Oxidative Cyclization of Tyrosine

The core hydroindole ring system of the Stemona alkaloids was prepared by oxidation of tyrosine with a hypervalent iodine reagent followed by a diastereotopic group-selective intramolecular conjugate addition.Further transformations illustrate the versati
