condensation process to prepare a labile β-(p-nitrophenyl)-α,β-unsaturated ketone system, along with development of a procedure for simultaneous hydrogenation/hydrogenolysis of olefin, benzyl ester, and nitro groups, allows the construction of an inexpensive route to 3-[2-(p-N-acetylaminophenyl)ethyl]-3-hydroxy-4-methylpentanoic acid, a key intermediate in the preparation of CI-1029 and related HIV protease
应用 Schopf 方法开发高收率缩合工艺以制备不稳定的 β-(对硝基苯基)-α,β-不饱和酮体系,同时开发烯烃苄酯同时加氢/氢解的工艺,和硝基基团,允许构建廉价的途径获得 3-[2-(pN-乙酰氨基苯基)乙基]-3-羟基-4-甲基戊酸,这是制备 CI-1029 和相关 HIV 蛋白酶抑制剂的关键中间体。
