Abstract
A new secobeyerenoic acid mono ester, ent-2,3-secobeyer-15-en-2,3-dioic acid, 3-methyl ester was isolated from the heartwood of Spirostachys africana and identified using spectroscopic methods. The mono ester was also prepared using two methods; by reacting the known diacid, ent-2,3-secobeyer-15-en-2,3-dioic acid with 1.5 mole equivalency of diazomethane, and methanolysis of ent-2,3-secobeyer-15-en-2,3-dioic anhydride.
