Date Jun. 22, 1995The invention relates to vitamin D amine and amide derivatives of general formula (I) where R represents a hydrogen atom, an aliphatic, cycloaliphatic or araliphatic group, or an acyl group comprising an aliphatic, cycloaliphatic, arylaliphatic or aryl group linked to the ...
Amides form strong intermolecular hydrogen bonds between the amide hydrogen atom of one molecule and the carbonyl oxygen atom of a second molecule (C=O⋯H—N). Thisintermolecular interactionis responsible for the high melting and boiling points of primary amides. Substitution of the hydrogen atoms...
