The synthesis of the new C-nucleoside 6-deazaformycin A was achieved through the condensation of a suitably substituted lithiated 2-picoline with 2,3,5-tri-O-benzyl-D-ribonolactone, borohydride reduction of the resulting hemiacetals, followed by intramolecular Mitsunobu cyclization of the carbinols, manipulation of the protecting groups, and subsequent ring closure to result in the formation of 7-
通过适当取代的锂化 2-甲基吡啶与 2,3,5-三-O-苄基-D-核糖内酯缩合、硼氢化物还原得到的半缩醛,然后合成新的 C-核苷 6-脱氮甲霉素 A通过甲醇的分子内光信环化、保护基的操作和随后的闭环,形成 7-氨基-3-(β-D-呋喃核糖基)吡唑并[4,3-b]吡啶。
