## Abstract Reactive extraction is studied as a promising chiral separation technique for commercial production scale. For chiral separation of amines and amino alcohols, a chiral crown ether was identified as a versatile enantioselective extractant. In this paper, the influence of various process
The reaction of 1,3-disubstituted uracils possessing an electron withdrawing group at the 5-position with amines induced exchange of Nl-portion of the uracil ring for amines. This reaction was accelerated by substitution of phenyl groups at the Nl-position.
