4′-C-methylene-linked bicyclic furanose moiety, are synthesized via the 3′-azido-3′-deoxy-4′-C-hydroxymethyl nucleoside 16. The β-D-ribo-configured derivative 4 is shown by NOE experiments to exist in a north-type (3E, C3′-endo) conformation and the α-L-xylo-configured derivative 5 in a south-type (3E, C3′-exo) conformation. Both nucleosides were devoid of anti-HIV activity in MT-4 cells.
通过3'-叠氮基-3'-脱氧-4'- C-羟甲基合成两个构象锁定的AZT类似物4和5,每个类似物均含有2'- O,4' - C-亚甲基连接的双环呋喃糖部分。核苷16。所述β- d -核糖-构型衍生物4由NOE实验示于北-型存在(3 é,C3'-内)构象,并且α-大号-木糖-构型衍生物5在南型(3 E,C3'-外切)的构象。两个都核苷 在MT-4细胞中没有抗HIV活性。
