  Applications of Sugar Nitrones in Synthesis:  The Total Synthesis of (+)-Polyoxin J¹

  摘要：

  A convergent synthesis of the peptidyl nucleoside antibiotic (inhibitor of chitin biosynthesis) polyoxin J (2) by coupling of 5-O-carbamoyl polyoxamic acid (3) and thymine polyoxin C (4) is described. These compounds were prepared by chain elongation and amination of sugar-derived aldehydes employing their nitrones as iminium derivatives and the furan ring as a masked carboxyl. Thus, the stereoselective addition of 2-lithiofuran to the L-threose derived N-benzyl nitrone 5 followed by reduction of the resulting hydroxylamine to amine, carbamoylation of the free hydroxy group, and oxidative cleavage of the furan ring to the carboxylate group gave a protected derivative of 3 (30%). The same method was followed for the synthesis of the ribofuranosyl alpha-amino acid nucleoside 4 (12.6%) starting from the D-ribose derived nitrone 6. The final coupling was performed by the N-hydroxysuccinimide active ester method in DMSO with the Hunig base (i-Pr2EtNH) using a derivative of 3 and unprotected 4.

  The antifungal antibiotic, polyoxin J 1, has been obtained (46.4%) by the coupling of a protected derivative of 5-O-carbamoylpolyoxamic acid 2 with thymine polyoxin C 3 which were prepared by a stereoselective aminohomologation strategy of sugar aldehydes (L-threose and dialdo-D-ribofuranose) employing nitrones 4 and 5 as their iminium derivatives and furan as a carboxylate group equivalent.

  抗真菌抗生素聚氧菌素J1（46.4%）是通过将5-O-氨基甲酰聚氧胺酸2的受保护衍生物与胸腺嘧啶聚氧菌素C3偶联得到的，后者是通过糖醛（L-苏糖和二醛-D-呋喃核糖）的立体选择性氨基同源化策略制备的，其中使用硝酮4和5作为亚氨基衍生物，呋喃作为羧酸基团等价物。
