more congested backbone structure resulting from the ortho-connectivity pattern. Intriguingly, tert-butyl and phenyl sidechains offer complete control over the amide conformations; whereas arylopeptoid residues with tert-butyl sidechains adopt a 100 % cis amide conformation, the opposite 100 % trans amide conformation was observed in arylopeptoids with phenyl sidechains. The tert-butyl moiety can
