N ‐alkylated aromatic poly‐ and oligoamides are a particular class of abiotic foldamers that is deprived of the capability of forming intramolecular hydrogen‐bonding networks to stabilize their tri‐dimensional structure. The alkylation of the backbone amide nitrogen atoms greatly increases the chemical diversity accessible for aromatic poly‐ and oligoamides. However, the nature and the conformational preferences of the N , N ‐disubstituted amides profoundly modify the folding properties of these aromatic poly‐ and oligoamides. In this Review, representative members of this class of aromatic poly‐ and oligoamides will be highlighted, among them N ‐alkylated phenylene terephthalamides, benzanilides, pyridylamides, and aminomethyl benzamide oligomers. The principal synthetic pathways to the main classes of N ‐alkylated aromatic polyamides with narrow to broad molecular‐weight distribution, or oligoamides with specific sequences, will be detailed and their foldameric properties will be discussed. The Review will end by describing the few applications reported to date and future prospects for the field.
