On March 16, 2020, Xie, Tao; Zheng, Chaoying; Chen, Kuanwei; He, Haibing; Gao, Shuanhu published an article.Synthetic Route of 2873-29-2 The title of the article was Asymmetric Total Synthesis of the Complex Polycyclic Xanthone FD-594. And the article contained the following:
A highly convergent approach was developed to achieve the first asym. and scalable total synthesis of FD-594, a complex polycyclic xanthone natural product from Streptomyces sp. TA-0256, in a longest linear sequence (LLS) of 20 steps. The trans-9,10-dihydrophenanthrene-9,10-diol fragment (B-C-D ring) was generated through a new strategy involving asym. dihydroxylation followed by Cu-mediated oxidative cyclization. Late-stage stereoselective glycosylation assembled the angular hexacyclic framework with a β-linked 2,6-dideoxy trisaccharide fragment. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Synthetic Route of 2873-29-2
