摘要:
First representatives of 3,3'-bidiaziridines, viz., 1, 1 '-dialkyl - 3,3 '-bidiaziridines, were synthesized and isolated as mixtures of two diastereomers. In the case of Alk = Me, the diastereomers were separated. It was demonstrated by nuclear Overhauser effect experiments and X-ray diffraction analysis that the diastereomers are the racemate (rac-1R*,2R*,3S*, 1 'R*,2'R*,3' S*) and the meso-form (1S*,2S*,3R*, 1 'R*,2' R*,3' S*).
