Caesalpinia bonducella

Cassanes.— -Caesalpin (41), from Caesalpinia pulcherrima, possesses the cassane skeleton, and is thus related to the bitter principles isolated from the seeds of Caesalpinia bonducella. Cassminic acid is a minor constituent of the bark of Erythrophleum guineense. Spectroscopic measurements and an interrelationship with cassane-16,19-dioic acid have established " it as 6-oxo-7-hydroxycass-13-ene-16,19-dioic acid. N.m.r. measurements and bromination-dehydrobromina-tion studies are in accord with the axial 14a-configuration now accepted for the cassamic acid diterpenes. 

The only review of C-NMR results for the cassane series focused on a group of compounds from a non-Compositae source Caesalpinia bonducella) that were substitutionally distinct from those reported from Osteospermum 231).
