A and B, isolated from the Mediterranean coral Cladocora cespitosa, are novel sesterterpenoids whose structures were initially proposed as 1 and 2, respectively. These designations, however, subsequently came under doubt. In the present study, the synthesis of compounds 5 and 6 was undertaken. The physical properties of 5 and 6 were found to be identical to those of natural cladocorans A and B, whose
从地中海珊瑚Cladocora cespitosa分离出来的Cladocorans A和B是新颖的酯类萜类化合物,其结构最初被提议为1和2。然而,这些名称随后受到质疑。在本研究中,进行了化合物5和6的合成。发现5和6的物理性质与天然cladocorans A和B的物理性质相同,因此其结构分别为5和6。因此,清楚地表明,克拉多考兰B是肌苷二醇的烯属区域异构体,而克拉多考兰A是其乙酸盐。
