Abstract

In 1997, a Chinese group published the isolation of six new compounds from Clerodendrum indicum, one which had identical structure and relative stereochemistry to rengyolone. 5 The compound was named cleroindicin F by these authors reporting a specific rotation of [α] D 20 =−2.7 (c 0.016, MeOH). The rengyolone samples previously isolated did not present a significant value of optical activity and it is accepted that the natural compound occurs as a ...
