opened with an azide to yield a common aziridine intermediate 12. Throughopening of the aziridinering of 12 with either a carbon or a sulfur nucleophile, chiral epoxide precursors 4-6 could be prepared for various HIV protease inhibitors. Except for the final low melting epoxides 5 and 6, all intermediates were obtained as crystalline solids, thus the synthetic pathway can be easily applied to a large-scale
开发了有效的合成路线来制备大量(4-15 克)手性环氧化物 4-6 作为通用中间体,用于合成具有治疗意义的天冬氨酰蛋白酶抑制剂,例如 HIV 蛋白酶和 β-分泌酶。L-抗坏血酸的 C(2)-C(3) 双键的氧化裂解,然后进行官能团操作,制备了环氧化物 10,用叠氮化物打开环氧化物,得到常见的氮丙啶中间体 12。通过打开12 的氮丙啶环与碳或硫亲核试剂,手性环氧化物前体 4-6 可以制备各种 HIV 蛋白酶抑制剂。除了最终的低熔点环氧化物 5 和 6 外,所有中间体均以结晶固体形式获得,因此该合成途径可以很容易地应用于手性环氧化物的大规模合成。
