Deprotection and saponification of the latter led to aminodeoxyerythrose and to aminodeoxyribose derivatives as an equilibrium of pyrrolidinose equivalents, i.e., hemiaminals 14a, b, imines 14′a, b, and dimers 14″a,b, respectively (Scheme 3). Hydrocyanic acid addition to 11a, b led ultimately to the proline derivatives 16a, b (Scheme 2). Compound 11b proved to be an inhibitor of syncytium formation in AIDS-infected
酰基亚硝基亲二烯体4与N-(丁二烯基)吡咯烷酮衍生物2a,b的杂二狄尔斯-阿尔德环加成反应对恶嗪加合物5a,b具有完全的区域选择性(方案1)。顺序的渗透作用,对随后的二醇的保护以及NO键的还原给出了预期的半胱氨酸盐11a,b,其特征在于它们的结晶亚硫酸盐加合物12a,b(方案1和2))。后者的脱保护和皂化导致氨基脱氧赤藓糖和氨基脱氧核糖衍生物作为吡咯烷糖当量的平衡,即分别为半缩醛14a,b,亚胺14′a,b和二聚体14″ a,b(方案3)。向11a,b中添加氢氰酸最终导致脯氨酸衍生物16a,b(方案2)。化合物11b被证明是艾滋病感染细胞中合胞体形成的抑制剂。
