Six new compounds, cleroindicins A-F (1-6), were isolated from the aerial parts of Clerodendrum indicum and identified by spectral and chemical evidence. Cleroindicin A. proved to be a novel spirocompound.
Rengyol and seven related cyclohexylethanoid natural products have been synthesized in a stereocontrolled manner from a common starting material. In the present study the absolute configuration of the three chiral products has been determined and the first synthesis of a cyclohexylethanoid natural product bearing an oxetane ring has been accomplished.
