describes the determination of the absolute configurations of the guadinomines, which are novel cyclic guanidyl natural products that are inhibitors of the type III secretion system (TTSS) of bacteria. Any compound that interrupts the TTSS of bacteria is potentially an ideal anti-infectious drug. The reliable asymmetric synthesis of guadinomines has revealed their absolute configurations, which could
本文介绍了胍基亚胺的绝对构型的测定,其是细菌的III型分泌系统(TTSS)抑制剂的新型环状胍基天然产物。任何会中断细菌TTSS的化合物都可能是理想的抗感染药。可靠的不对称合成胍基亚胺揭示了它们的绝对构型,如果没有这种合成方法就无法确定。我们的报告不仅描述了标题化合物的不对称全合成,而且还证明了三取代的哌嗪酮核的新颖简明合成方法为光学纯形式。我们的方法的新功能是分子内S(N)2环化,使用PPh(3)和I(2)构造独特的5元环胍亚结构。
