functionalized analogues (−)-96 and (−)-97 afforded the corresponding dimers (−)-98 and (−)-99, respectively, under a variety of reaction conditions, even at concentrations of only 0.001 N. Consideration of factors affecting the conformation of amide bonds and their effects on cyclization reactions led us to alkylate the amide bond. As expected, the cyclization of the N-methyl derivative (−)-110 afforded exclusively
设计,合成并功能化了新的分子平台,该平台是两个支架(β- d-葡萄糖和苯并二氮杂hybrid)的杂交体,每个支架都可以结合几种蛋白质,可以用作广泛生物学筛选的探针。在这里,我们描述了这些新型嵌合支架的合成和化学性质。尝试将官能化的类似物(-)- 96和(-)- 97环化,得到相应的二聚体(-)- 98和(-)- 99在各种反应条件下,甚至在浓度仅为0.001 N的情况下也是如此。考虑到影响酰胺键构象的因素及其对环化反应的影响,我们使酰胺键烷基化。如所预期的,N-甲基衍生物(-)- 110的环化仅提供了单分子环化产物(+)- 111。这些化合物现在才进行广泛的筛选,因此目前代表着“勘探库”。
