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
