A New Convenient Synthesis of 2-Aryl- and 2-Heteroaryloxazolo<5,4-b>pyridines

Several 2-aryl- and 2-heteroaryloxazolo<5,4-b>pyridines were synthesized in high yields from 3-(arylcarbonylamino)-2-chloropyridines by heating in the presence of trimethylsilylpolyphosphate ester.

The unambiguous synthesis and NMR assignment of 4-alkoxy and 3-alkylquinazolines

Contrary to a number of reports, alkylations of the privileged 3,4-dihydroquinazoline scaffold provide N3-alkylated products, and not 4-alkoxyquinazolines. To correctly assign the structure, 13C NMR shifts of the -Z-CHn- (Z=O, N) fragment are necessary; resonances in the 45-55 ppm range are indicative of N3-alkylation. Treatment of 3,4-dihydroquinazoline-4-one with p-TsCl afforded the N3-tosylated compound, whose reaction with an amine yielded the corresponding N3-alkyl derivative. A mechanism corroborated by 15N-labeling involving pyrimidine ring opening and recyclisation is proposed. Finally, the unambiguous preparation of 4-alkoxyquinazolines is described via treatment of 3,4-dihydroquinazoline-4-ones with PCl5 followed by an alkoxide.

EXCITED-STATE DIPOLE MOMENT AND SOLVATOCHROMISM OF HIGHLY FLUORESCENT ROD-SHAPED BICHROMOPHORIC MOLECULES.

Efficient photoinduced charge separation can occur in molecules containing electron donor (D) and acceptor (A) groups separated by an elongated paraffinic spacer. For two molecules of this type the dipole moment of the excited state thus achieved (D** plus -A** minus ) is shown to be as high as 25 plus or minus 2 D via nanosecond time-resolved microwave conductivity measurements. Despite the lack of either direct D/A contact or coupling via a pi -electron system the dipolar excited states are found to emit charge-transfer-type fluorescence with a quantum yield exceeding 50% in some solvents. The enormous solvatochromism of this fluorescence makes these molecules attractive as fluorescent polarity probes.

Current advances in the synthesis and biological evaluation of pharmacologically relevant 1,2,4,5-tetrasubstituted-1H-imidazole derivatives

In recent years, the synthesis and evaluation of the biological properties of 1,2,4,5-tetrasubstituted-1H-imidazole derivatives have been the subject of a large number of studies by academia and industry. In these studies it has been shown that this large and highly differentiated class of heteroarene derivatives includes high valuable compounds having important biological and pharmacological properties such as antibacterial, antifungal, anthelmintic, anti-inflammatory, anticancer, antiviral, antihypertensive, cholesterol-lowering, antifibrotic, antiuricemic, antidiabetic, antileishmanial and antiulcer activities. The present review with 411 references, in which we focused on the literature data published mainly from 2011 to 2017, aims to update the readers on the recent developments on the synthesis and biological evaluation of pharmacologically relevant 1,2,4,5-tetrasubstituted-1H-imidazole derivatives with an emphasis on their different molecular targets and their potential use as drugs to treat various types of diseases. Reference was also made to substantial literature data acquired before 2011 in this burgeoning research area.
