Chiral diamides and tetramidic resorcin[4]arenes deriving from (R,R)-1,2-diaminocyclohexane and (S,S)-1,2-diphenylethylendiamine, and a valine contg. resorcin[4]arene have been compared by NMR in the enantiodiscrimination of mandelic acid. The relevance of cooperation between side arms and external surface of resorcin[4]arene core has been ascertained.

Abstract
Chiral diamides and tetramidic resorcin[4]arenes deriving from (R,R)-1,2-diaminocyclohexane and (S,S)-1,2-diphenylethylendiamine, and a valine contg. resorcin[4]arene have been compared by NMR in the enantiodiscrimination of mandelic acid. The relevance of cooperation between side arms and external surface of resorcin[4]arene core has been ascertained.File in questo prodotto:
