for several biological targets. Formation by cyclodehydration from their monoacylated counterparts was shown to be strongly dependent upon the nature of the acyl group. In the case of a dicyclohexylmethyl group, cyclization was only observed in a p-toluenesulfonic acid/toluene mixture from the symmetrical diacylated precursor. Analysis of the mechanism was begun starting from mixed diacylated derivatives
设计了一系列大体积的2-取代的苯并咪唑,以便为几个生物学靶标找到新的潜在客户。由它们的单酰化的对应物通过环脱水形成显示出强烈地依赖于酰基的性质。在二环己基甲基的情况下,仅在对称二酰基化前体的对甲苯磺酸/甲苯混合物中观察到环化。从混合二酰化衍生物开始分析机理。
