prepared starting from 3-iodo-phenylalanine. Macrocyclization of alkene phenyl iodide 5 was effected through a palladium-catalyzed Heck reaction. The macrocyclic alpha-ketoamides were active inhibitors of the HCV NS3 protease, with the C-terminal acids and amides being more potent than tert-butyl esters.
从3-碘-苯丙氨酸开始制备基于17元的苯丙氨酸的大环化合物6。烯基苯基碘化物5的大环化是通过钯催化的Heck反应进行的。大环α-酮酰胺是HCV NS3蛋白酶的活性抑制剂,其C端酸和酰胺比叔丁酯更有效。
