New Synthetic Methods for N-Aryl-N-Hydroxymethyl Amides and Methylenebisamides

Aryl or heteroaryl amides of tetrahydronaphthalene, chroman, thiochroman and 1,2,3,4-tetrahydroquinoline carboxylic acids having retinoid-like biological activity.

CH 2 groups were replaced by NH or o and vice versa, nitro groups became carboxylic acids and amides, OH groups became fluorine atoms; the list is extensive.

"There are no practical natural sources of simple covalent amides, But the peptides and proteins in living systems are long chains (polymers) with peptide Bonds (see covalent Bond), which are amide linkages."
