Abstract: | Summary The stereochemical correlation of olivin with chromomycinone and the directed degradation of the first of them to di-O-methyl-D-tartaric acid (XXI) has been effected. As a result, it has been shown that olivin and chromomycinone both have the absolute configuration 2S,3R,1S,3S,4R and possess the respective structures (Ia) and (Ib).For Communication XXV, see [1], and for a preliminary communication see [2].M.
