Furthermore, it was found that AB-functionalized building blocks were prone to intramolecular cyclization on the DNA template, whereas much better intermolecular coupling efficiences were achieved by using mixtures of AA-and BB-modified building blocks. A range of coupling chemistries were explored, including amine acylation, reductive amination, hydrazine formation ...
