Abstract
We were able now to demonstrate that the pseudobases (6-hydroxyderivatives) are the only products of alkalization of the QBA in DMSO-d6 solution using sodium carbonate. In less-polar environment the pseudobases are further converted into bimolecular aminoacetals, which exist in two diastereomeric forms. The detailed configurational and conformational analysis of bimolecular aminoacetals, based on NMR measurements, quantum chemical calculations, and X-ray analysis was presented.
