Abstract

A new 2-acylindole alkaloid, pagicerine (1) has been isolated from the stem bark of Pagiantha cerifera (Pancher et Sébert) Markgraf. Its structure has been elucidated on the basis of spectroscopic analyses. It is the first indole alkaloid to present an additional tetrahydro-1,3-oxazine ring.
