The peptide BOC-L-Val-APhe-APhe-L-Val-OCH3 was synthesized by the azlactone method in solution phase, and its crystal and molecular structures were determined by x-ray diffraction method. Single crystals were grown by slow evaporation from a methanol/water solution at 6°C. The crystals belong to an

## Abstract The peptide N‐Ac‐dehydro‐Phe‐L‐Val‐L‐Val‐OCH~3~ (C~22~H~31~N~3~O~5~) was synthesized by the usual workup procedure and finally by coupling the N‐Ac‐dehydro‐Phe‐L‐Val‐OH to valine methyl ester. It was crystallized from its solution in acetonitrile‐water mixture at 4°C. The crystals belon
