group was synthesized starting from an optically active bicyclo[2.2.1]heptane compound, which was then used to build the 5 atoms ring of a key 6-chloropurine intermediate. This was then reacted with ammonia and selected amines obtaining new adenine- and 6-substituted adenine conformationally constrained carbocyclic nucleoside analogues with a bicyclo[2.2.1]heptane skeleton in the sugar moiety. X-ray crystallography
从旋光性双环[2.2.1]庚烷化合物开始合成胺基,然后将其用于构建关键的6-氯嘌呤中间体的5个原子环。然后使其与氨和选定的胺反应,得到新的腺嘌呤和6-取代的腺嘌呤构象受限的碳环核苷类似物,其糖部分具有双环[2.2.1]庚烷骨架。X射线晶体学证实了碱基与环的外耦合以及核苷类似物的L构型。测试化合物的抗癌活性。
