An uncomplicated, high-yielding synthetic route has been developed to constitute complicated heterocycles, applying domino, click and retro-Diels–Alder (RDA) reaction sequences. Starting from 2-aminocarboxamides, a new set of isoindolo[2,1-a]quinazolinones was synthesized with domino ring closure. A click reaction was performed to create the 1,2,3-triazole heterocyclic ring, followed by an RDA reaction resulting in dihydropyrimido[2,1-a]isoindole-2,6-diones. The absolute configuration, concluded by the norbornene structure that served as a chiral source, remained constant throughout the transformations. The structure of the synthesized compounds was examined by1H and13C Nuclear Magnetic Resonance (NMR) methods.

A highly robust 6-strand transforms into a right-handed 10-helix through the substitution of 14-helical nucleating residues at alternate positions along the backbone of the oligomer has been reported. The heterooligomers, tetramer and hexamer with NAA and
