  Synthesis and Properties of C-Azalyxonucleosides

  摘要：

  1-beta-(4-Imidazoyl)- and 1-beta-(5-uracilyl)-1,4-dideoxy-1,4-imino-L-lyxitols were synthesized stereoselectively via a sequential procedure by the addition of the corresponding metal salts of heterocycles, Swern oxidation, reductive aminocyclization, and deprotection. Their structures were determined based on X-ray crystallography. From the NMR measurements of their N-acyl derivatives, two rotational isomers were observed. Their bioassay is also described.
