Diastereoselective Cyclization of a Glycyl-alanine Azomethine to an Imidazolidinone: Determination of the Product Configuration by X-Ray Analysis
Glycyl-(5')-alanine-esters 1 and 2 can be condensed to the corresponding 4-oxo-imidazolidin-3-yl-propionates 3 and 4, respectively. The diastereomers 3a and 4a are formed preferentially and the configuration was found to be u by single crystal X-ray diffraction of 4a. The crystal structure sho...
