title: Structure of Boc-Phe-D-Leu-Thr-OMe.
abstract: The X-ray crystal structure analysis shows that tert-butoxycarbonyl-L-phenylalanyl-D-leucine-L-threonine methyl ester takes an open conformation in which the tert-butoxycarbonyl group is located face-to-face with the D-leucine isobutyl side chain. In the crystal, the molecules, translated by twofold screw symmetry, form an infinite sheet structure through four independent hydrogen bonds.
