Synthesis, Crystal and Molecular Structure of Novel Adamantyl Derivatives of N-Aryl Substituted 3-Hydroxy-2-methylpyridine-4-ones

Two novel potentially bioactive compounds, esters 2-methyl-1-phenylpyridine-4-one-3-yl adamantan-1-ylethanoate (1) and 1-(p-methoxyphenyl)-2-methylpyridine-4-one-3-yl adamantan-1-ylethanoate (2), were synthesized by esterification of adamantan-1-ylacetic acid with appropriate N-aryl substituted 3-hydroxypyridine-4-one derivatives. Both compounds are fully characterized using standard spectroscopic methods. Crystal and molecular structures of 1 and 2 were determined by the single crystal X-ray diffraction method. The crystal packing of both 1 and 2 shows separation of the hydrophobic and hydrophilic regions. The crystal structure of 1 is characterized by the two-dimensional hydrogen bonding layers parallel to (001). The crystal packing of 2 is characterized by hydrogen-bonded chains extended in the direction [010].
