The selective synthesis of ultrahigh-molar-mass (UHMM, >2millionDa) cyclic polymers is challenging as an exceptional degree of spatiotemporal control is required to overcome the possible undesired reactions that can compete with the desired intramolecular cyclization. Here we present a counterintuitive ...
Compounds 1 (1,2-bis[4-oxo-4H-1-benzopyran-3-ylmethylenamino]-ethanes) and 2 (3-((E)-(3-(dimethylamino) propylimino)methyl)-4H-chromen-4-one) were synthesized using a one pot condensation reaction between 3-formylchromone and ethylenediamine/N,N-dimethylpropylamine, respectively. Compounds...
