A general route which provides direct access to pyroglutamates from tetramates, making use of Suzuki coupling on an enol mesylate, followed by reduction, is reported. This work permits direct scaffold hopping from tetramate to substituted pyroglutamates. Some compounds in the library showed modest antibacterial activity against Gram-positive bacteria.
据报道,通过使用在烯醇甲磺酸酯上的Suzuki偶联,然后通过还原,可以从四酸酯直接获得焦谷氨酸酯的一般路线。这项工作允许直接支架从四酸酯跳到取代的焦谷氨酸酯。文库中的某些化合物显示出对革兰氏阳性细菌的适度抗菌活性。
