The use of the 2-(diphenylphosphino)ethyl group for carboxyl-protection of amino acids or peptides is described. This group is easily introduced by esterification using 2-(diphenylphosphino) ethanol in the presence of dicyclohexylcarbodiimide and 4-(dimethylamino)pyridine. These Dppe esters are stable under the standard conditions for peptide synthesis. Deprotection is carried out under mild conditions
描述了将2-(二苯基膦基)乙基用于氨基酸或肽的羧基保护。通过在二环己基碳二亚胺和4-(二甲基氨基)吡啶的存在下使用2-(二苯基膦基)乙醇进行酯化容易地引入该基团。这些Dppe酯在用于肽合成的标准条件下是稳定的。脱保护是在温和条件下进行的,方法是使用甲基碘进行季铵化,然后通过氟离子或碳酸钾诱导β消除。
