[structure: see text] The synthesis of a new family of densely functionalized oxazole-containing amino acids is described. These building blocks were employed for preparing macrocycles containing Lys and Glu residues by a combination of solid- and solution-phase synthesis. The resulting structures are presented as orthogonallyprotectedscaffolds for supramolecular chemistry.

stemming from BP-HSA to be recognized by naı̈ve CD4+ T-cells thus identifying a pre-existing T-cell repertoire for penicillin molecules bound to proteins. It also established a promising model approach expandable to other most frequently used penicillin classes of antibiotics to reveal biomimetic drug-modified antigenic peptides relevant for qualitative and quantitative drug allergy studies.

The preparation of N-protected amino/peptide alpha-cyanomethyl ketones through cyanation of the corresponding alpha-bromomethyl ketones is described. The utility of the resulting acyanomethyl ketones in the synthesis of 3-substituted-5-amino-1H-pyrazoles has also been demonstrated. In both steps a wide range of N-protected amino/peptide acids has been employed and the products are obtained in good yield. The enantiomeric purity of both the alpha-cyanomethyl ketones and pyrazoles were confirmed by chiral HPLC analysis of the corresponding Z-protected D-and L-Ala-OH as model substrates. The synthesis of peptide pyrazolecarbox-amides is also delineated.

Short peptides are extremely important as drugs and building blocks for the syntheses of longer peptides. Both solid- and liquid-phase peptide syntheses suffer from a large number of synthetic steps, high cost, and/or tedious purification. Here, we developed a rapid, mild, inexpensive, and column-chromatography-free peptide chain elongation via a one-flow, three-component coupling (3CC) approach that
