The synthesis of phosphonate derivatives of N-phenyl- and N-benzyl-gamma- and delta-sultams, and their application in the Wittig-Horner reaction with N-Boc-L-phenylalanine aldehyde to afford E- and Z-isomers, are described. These compounds were further processed to provide five dipeptide vinyl sultams, which were found to be inactive against papain at concentrations up to 50 microM. In contrast, vinyl
N-苯基-和N-苄基-γ-和δ-杜鹃花的膦酸酯衍生物的合成及其在与N-Boc-L-苯丙氨酸醛提供E-和Z-异构体的Wittig-Horner反应中的应用描述。这些化合物被进一步加工以提供五种二肽乙烯基sultams,发现它们在高达50 microM的浓度下对木瓜蛋白酶无活性。相比之下,乙烯基sultams对重组falcipain-2和恶性疟原虫W2的活性较弱。
