چکیده
Crystals of the title compound, C(57)H(85)N(9)O(9)·CH(4)O, the methanol solvate of a nine peptide polypeptide, cyclo-(Pro-Pro-Phe-Phe-Leu-Ile-Ile-Leu-Val), were obtained after separation of the cyclic peptide from flax oil. The cyclo-linopeptide A (CLP-A) mol-ecules are linked in chains along the a axis by N-H⋯O hydrogen bonds. Each methanol O atom is hydrogen bonded to one O atom and two N-H groups in the same CLP-A mol-ecule. There are a total of eight hydrogen bonds in each CLP-A-MeOH unit.

In the title methanol solvate, C(20)H(24)N(2)O(2)·CH(4)O, an L-shaped conformation is found as the two substituents at the central hydr-oxy group are almost orthogonal to each other [the C-C-C angle at the central sp(3)-C atom is 110.12 (13)°]. The most notable feature of the crystal packing is the formation of supra-molecular chains along the b direction mediated by O-H⋯N hydrogen bonds occurr...

The title compound, crystallized as a methanol solvate, C(18)H(20)O(2)·CH(3)OH, is an inter-mediate in the synthesis of the anti-lipidemic agent clinofibrate. Mol-ecules are packed together with the methanol solvent molecule via two O-H⋯O hydrogen bonds. The third O-H⋯O hydrogen bond is between neighboring 4,4'-(cyclo-hexane-1,1-di-yl)diphenol mol-ecules. The dihedral angle between two benzene ...
