Synthesis, photophysical properties, and application of o - And p -amino green fluorescence protein synthetic chromophores

The o- and p-amino green-fluorescence-protein synthetic chromophores (GFPSCs) were synthesized from the corresponding o- and p-nitro protecting group. Among the four protecting groups of the o-amino group, the o-nitro protecting group is the only choice to synthesize the o-amino GFPSCs. The first singlet excited states of o- and p-amino GFPSCs carry significant charge-transfer character through the mechanism of photoinduced charge transfer (PCT). The o-amino GFPSCs can serve as wavelength-ratiometric fluorescence sensors that selectively recognize Cr3+ in aqueous medium through a PCT mechanism.

Cyclocondensation reactions of heterocyclic carbonyl compounds XI [1]. Synthesis and study of cyclocondensation reactions of some 3-substituted-5-(2- aminobenzyl)-1H-[1,2,4]triazine-6-ones

A series of 2-substituted-4-(2-nitrobenzylidene)-4,5-dihydrooxazol-5-ones (2a-2i) was prepared by the Erlenmeyer's synthesis of 2-nitrobenzaldehyde with acylglycines (1a-1i) and the series of corresponding aminoderivatives (3b-3d and 3g-3i) was synthetise

Keto/enol tautomerism in phenylpyruvic acids: Structure of the o- nitrophenylpyruvic acid

The synthesis of a tautomeric keto/enol mixture of o-nitrophenylpyruvic acid followed the acid hydrolysis of the azlactone of o-nitrobenzaldehyde was carried out. The structures of the two tautomeric forms were assigned by NMR spectroscopy. X-ray diffraction of a single crystal revealed that the crystalline form corresponds to the keto tautomer. Quantum mechanics calculations in the gas phase confirmed the experimental findings in solution. (C) 2000 Elsevier Science B.V.
