For the first time, spontaneous resolution of trans-dihydroxyimidazolidin-2-one 1a was performed and racemisation of (-)-1a was studied; regiospecific reaction of 1a-c with aminoguanidine resulted in derivatives 2a-c; compound 2b was also shown to undergo spontaneous resolution, and the absolute configuration (4R,5R) of (-)-2b crystals was established by X-ray diffraction analysis.
