Synthesis of Water-Soluble Blue-Emissive Tricyclic 2-Aminopyridinium Salts by Three-Component Coupling-(3+3)-Anellation

The (3+3) anellation of alkynones and cyclic amidines is a novel and unexpected approach to generate intensively blue luminescent tricyclic 2-aminopyridinium salts with quantum yields Φf up to 63 % in water. By implementation into a consecutive three-component reaction, these title compounds are obtained rapidly and efficiently in a diversity-oriented fashion. Most interestingly, these bi- and tricyclic 2-aminopyridinium salts emit in dichloromethane and water solutions, thus making them interesting novel luminophore probes for bioanalytics, as well as in the solid state, thus making them blue emitters with tunable efficiency.

1-(Phenylethynyl)aziridine in reactions with amines

The reaction of 1-(phenylethynyl)aziridine with a primary or secondary amine gave 2-benzylimidazoline-2 or N-aminoethyl substituted phenylacetamidine via nucleophilic attack on the aziridine ring. The mechanism of aziridine ring opening by an amine was studied.

2-Alkylidenimidazolidine - Synthesis, Basicity, 1H- and 13C-NMR Spectra

4,5-Dihydroimidazolium salts 2, 3, and 4 were synthesized by carefully directed alkylation of 4,5-dihydroimidazoles 7 and 8. 2, 3, and 4 were deprotonated by sodium hydride to yield 2-alkylideneimidazolidines 1. 1H and 13C-NMR spectra allow to assign the
