Synthesis and absolute configuration of (−)-chettaphanin I and (−)-chettaphanin II

An efficient synthesis of chettaphanin I and II has been achieved from ent-halimic acid. The absolute configuration of the natural products was established by nOe experiment and by X-ray analysis of chettaphanin II. The absolute configuration of chettaphanin I and II has been established by synthesi...
