  Total syntheses of (-)-acetomycin and its three stereoisomers at C-4 and C-5

  摘要：

  The total synthesis of the antitumor and antimicrobial agent (-)-acetomycin (1) from the previously reported tetrahydrofuran 10, a derivative Of D-glucose is described. Reactions which altered only the side chains of 10 gave the substituted tetrahydrofuran 20, which was then converted into the acyclic alcohol 38 and oxidized to the corresponding carboxylic acid 39. Ozonolysis of the vinyl group of 39 gave an aldehyde, spontaneous cyclization of which afforded a 5:1 mixture of the diastereomeric gamma-hydroxy gamma-lactone 40. Treatment of the mixture with acetic anhydride in pyridine gave predominantly (>45:1) the alpha-acetate 41. On the other hand, treatment of compounds 40 with methanesulfonyl chloride/triethylamine in benzene, followed by treatment of the mixture of mesylates so formed with silver acetate and tetrabutylammonium acetate, resulted in the formation of a 1.3:1 mixture of 41 and the beta-acetate 42. Removal of the MOM protecting group of 41 and 42 and pyridinium chlorochromate (PCC) oxidation of the products gave (+)-5-epi-acetomycin (2) and 1, respectively. In a similar manner, (-)-4-epi-acetomycin (3) and (+)-4,5-di-epi-acetomycin (4) were synthesized from the substituted tetrahydrofuran 11. The results of preliminary studies of the in vitro inhibitory effects of compounds 2-4 on the growth of several tumor cells are also presented.
