(E)-N-Benzolydehydro-3-(3-pyridyl)-alanyltryptophan was synthesized in 89% yield by the reaction of 2-phenyl-4-(3-pyridylidene)-5(4H)-oxazolone with tryptophan. The reaction of 4-[1-(2-furyliden)ethyl]- and 4-(3-pyridyliden)2-phenyl-5(4H)-oxazolones with alanyltryptophan gives a mixture of theZ andE isomers of the corresponding dehydrotripeptides. Racemization of the alanyl and tryptophan residues was not observed. |
