Two new rearranged diterpenoids, tomocinol C(1) and spirocaesalmin C(2) were isolated from the seeds of Caesalpinia sappan. Their structures were elucidated based on comprehensive analysis of spectroscopic data, and their absolute configurations were established by single crystal X-ray crystallography.
