Appropriately protected seryldipeptides which have a relatively acidic proton (H1 of 1) on the α' C can be efficiently converted to β-lactams by reaction with azodicarboxylates and triphenylphosphine. Application of the same reaction conditions to serylamides which lack an acidic α' proton provided dehydropeptides as the major product. Model reactions and potential intermediates which rationalize these
通过与偶氮二羧酸酯和三苯基膦反应,在α'C上具有相对酸性质子(H 1为1)的适当保护的丝氨二肽可以有效地转化为β-内酰胺。将相同的反应条件应用于缺少酸性α'质子的丝氨酰胺可提供脱氢肽作为主要产物。描述了使这些结果合理化的模型反应和潜在的中间体。
