Stereochemical control in the biomimetic conversion of heteroyohimbine alkaloid precursors. Isolation of a novel key intermediate
Abstract
The isolation of a novel key intermediate (3) related to cathenamine (4) and its conversion in a stereo-selective sequence of reactions into tetrahydroalstonine (8) and 19-epiajmalicine (10) afford new information concerning the biosynthesis of heteroyohimbine alkaloids.
