(−)-Neplanocin C (4), a minor component of the neplanocin family of antibiotics and a lead drug for the design of several conformationally constrained nucleosides analogues, was enantioselectively synthesized starting from d-ribono-1,4-lactone via a convergent approach in twelve steps. The proton NMR spectrum of 4 was in agreement with the corresponding natural product. Calculated coupling constants
(-)-Neplanocin C(4)是neplanocin家族中的次要成分,是用于设计几种构象受限的核苷类似物的先导药物,它是通过d-ribono-1,4-lactone通过聚合反应从对映体上选择性合成的十二步走。的质子NMR谱4是在与相应的天然产物一致。从头算分子模型研究和先前发表的奈普拉辛C的X射线结构获得的计算耦合常数也与光谱数据相对应。
