The solid and solution state conformation of yunnanin A, a cyclic heptapeptide, cyclo(-Gly-Tyr-Gly-Gly-Pro-Phe-Pro-), isolated from the roots of Stellariu yunnanensis were studied. The X-ray diffraction studies showed that the crystal of yunnanin A [orthorhombic form from a ethanol-methanol mixture,

The aza-tripeptide Boc-Ala-AzPip-Ala-NHiPr (AzPip: 2-aza pipecolyl residue) was synthesized in seven steps using preferentially the diisopropylcarbodiimide/1-hydroxy-7-aza-benzotriazole (DIPCDI/AtOH) coupling method and via the Boc-AzPip-OBzl pivotal intermediate. Its crystal molecular structure is
