摘要
For the first time, a number of new 3,3-dimethyl-1,5-diazabicyclo[3.1.0]hexanes has been obtained and characterized by X-ray diffraction analysis, spectral and physicochemical methods. The features of the enantiomers of the considered compounds are analysed by quantum chemistry methods and crystal packing modeling methods. It is shown that intermolecular interactions in solid state radically change the nature of the conformational structure of 1,5-diazabicyclo[3.1.0]hexanes. (C) 2022 Elsevier B.V. All rights reserved.
