The pot, atom, and step-economic synthesis of Rosettacin topo-I poison and its derivatives has been achieved using a novel domino N-amidoacylation/aldol-type condensation, followed by decarboxylation of the ester function. The key domino procedure simply involves mixing HOBt ester as new reagent with lactam and NaH together in THF or THF/ DMF. The reaction seems to be general and led to suitable N-heterocyclic
Rosettacin topo-I毒物及其衍生物的锅,原子和逐步经济合成已使用新型的多米诺骨牌N-酰胺酰化/醛醇缩合,然后酯功能脱羧而实现。关键的多米诺骨牌程序仅涉及将作为新试剂的HOBt酯与内酰胺和NaH一起混合在THF或THF / DMF中。该反应似乎是普遍的,并导致中等至良好产率的合适的N-杂环产物。
