摘要
The absolute configuration of polycephalin C(1) isolated from plasmodia of the slime mold Physarum polycephalum is supposed to be 3"R,4"R as found by comparison of CD spectra of the natural product polycephalin C(1) and CD spectra of synthetic bis-benzoates (-)4 and (+)-4. An X-ray structure of the corresponding bis-camphanate (+)-3 shows that the exciton chirality method may not be applied on these 1,4-diols in the usual manner.
