A concise synthetic route has been developed for the preparation of a constrained peptidomimetic pyrazinone building block. From hydroxy-L-lysine, the desired pyrazinone is obtained in 43% overall yield (6 steps) via an efficient deprotection–double cyclization sequence.
我们开发了一条简洁的合成路线,用于制备受限的拟肽吡嗪酮结构单元。以羟基-L-赖氨酸为原料,通过高效的脱保护-双环化顺序,以 43% 的总收率(6 个步骤)获得了所需的吡嗪酮。
