A[P.Rajakumar,A.M.A.Rasheed,Tetrahedron 61(22)(2005)5351]para-cyclophane derivative was synthesized viaintramolecular esterification of a dipeptide surrogate containing asparagine to form tetrahydropyrimidinone ring.The structuresof the product and intermediates were characterized by1H NMR,13C NMR and mass spectrum.
