The present invention relates to an efficient procedure for the synthesis of deserpidine (Ia), starting from reserpic acid lactone (II) via the intermediate 11-O-demethyl reserpic acid lactone (III).
The Rauwolfiaalkaloidsreserpine (1) and deserpidine (2), two alkaloids from Rauwolfia species, have been widely used for their antihypertensive action. Deserpidine (2) is a compound with limited availability from natural sources, and its synthesis from 1 in six steps (41% overall yield) is reported here.
