5-Benzoyl-5-deacetylwilforidine : A new sesquiterpene nicotinoyl alkaloid from Maytenus buchananii

A new sesquiterpene nicotinoyl alkaloid has been isolated from Maytenus buchananii (Loes.) R. Wilczek and identified as 5-benzoyl-5-deacetylwilforidine (1). This appears to be the first sesquiterpene nicotinoyl alkaloid based on hydroxywilfordic acid with a benzoyl group at C-5.
