intermediates were elaborated further by deprotection and cleavage of the N–N bond to provide useful building blocks for aspartic protease inhibitors. Coupling of the compounds 76–86 with the mono-isophthalamide 91 provided moderate inhibitors of human β-secretase (BACE) 92–102. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
重氮二羧酸酯对醛的对映选择性有机催化 α-胺化反应与 Passerini 反应相结合,可以快速获得基于诺斯他汀的肽模拟物。这些中间体通过 N-N 键的脱保护和裂解进一步加工,为天冬氨酸蛋白酶抑制剂提供有用的构建块。化合物 76-86 与单间苯二甲酰胺 91 的偶联提供了人 β-分泌酶 (BACE) 92-102 的中度抑制剂。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
