Abstract

Investigation of the dehydrogenative conversion of indolines into indoles with benzeneseleninic anhydride (1) resulted in the development of an efficient standardised procedure, which was successfully applied to the final steps in first total synthesis of (±)-lysergol (18), (±)-isolysergol (27), and (±)-elymoclavine (29).
