3-(hydroxyalkyl)-N,N′-disubstituted 2,5-diketopiperazine derivatives - compounds required for the bicyclomycin analogues preparation - has been studied. The use of various oxo components in the Ugi multicomponent reaction (U-MCR) has been evaluated. The first example of an semicyclic O,O-acetal employed as an aldehyde equivalent in the U-MCR has been reported. The preparation and the synthetic application of
已经研究了3-(羟烷基)-N,N′-二取代的2,5-二酮哌嗪衍生物(双环霉素类似物制备所需的化合物)的合成。已评估了在Ugi多组分反应(U-MCR)中使用各种羰基合成物。已经报道了在U-MCR中用作醛当量的半环O,O-缩醛的第一个例子。还描述了在2,5-二酮哌嗪骨架的合成中Wang树脂结合的脂族醛的制备和合成应用。
