The isolation of cleroindicins B, C and cleroindicin E, together with three novel related compounds cleroindicins A, D and F, from chinese folk medicine Clerodendrum indicum Linn. was reported before1. Pharmaceutical studies showed that cleroindicin C has certain anticancer activity, so its total synthesis attracted our considerable interest.Cleroindicin B Cleroindicin C Cleroindicin EThe commercially available 2-(p-methoxyphenyl) ethanol 1 was selected as the starting material.
