Triphenylphosphine-free approach for one-pot N-alkylation of purine, pyrimidine, and azole derivatives with alcohols using P2O5/KI: A facile and selective route to access carboacyclic nucleosides

A facile, selective, and mild synthetic approach for one-pot N-alkylation of nucleobases and other related N-heterocycles via alcohols, using a mixture of P2O5 and KI is described. The reaction of structurally diverse purines, pyrimidines, and/or azoles with primary alcohols with the use of P2O5/KI and basic mixture of Et3N/K2CO3 in refluxing DMF affords the corresponding N-alkyl derivatives (carboacyclic nucleosides) in good to reasonable yields. The influence of different parameters comprising solvent, base, temperature, and substrate/reagent ratios was assessed on the reaction progress. The secondary and tertiary alcohols were failed to react with nucleobases. The main advantageous of current protocol is formation of water soluble side products in which provides simple work-up and purification processes.

Photoisomerization of Cyanines. A Comparative Study of Oxygen- and Sulfur-Containing Species

We have compared the photoisomerization properties of two cyanine analogs, 3,3′-diethyloxadicarbocyanine iodide (DODCI) and 3,3′-diethylthiadicarbocyanine iodide (DTDCI).These two molecules are structurally similar, differing oly in the presence of oxygen or sulfur at two heteroatom sites.Measurement of the radiative an nonradiative population relaxation kinetics of these molecules reveals a difference in their equilibrium geometries despite their outward similarities.We relate this difference to the steric constraints imposed by the oxygen and sulfur heteroatoms and to the occurrence of an excited state barrier predicted by semiempirical calculations of the ground- and excited-state isomerization surfaces for these molecules.

Improving the fatigue resistance of diarylethene switches

When applying photochromic switches as functional units in light-responsive materials or devices, an often disregarded yet crucial property is their resistance to fatigue during photoisomerization. In the large family of diarylethene photoswitches, formation of an annulated isomer as a byproduct of the photochromic reaction turns out to prevent the desired high reversibility for many different derivatives. To overcome this general problem, we have synthesized and thoroughly investigated the fatigue behavior of a series of diarylethenes, varying the nature of the hetaryl moieties, the bridging units, and the substituents. By analysis of photokinetic data, a quantification of the tendency for byproduct formation in terms of quantum yields could be achieved, and a strong dependency on the electronic properties of the substituents was observed. In particular, substitution with 3,5-bis(trifluoromethyl)phenyl or 3,5-bis(pentafluorosulfanyl)phenyl groups strongly suppresses the byproduct formation and opens up a general strategy to construct highly fatigue-resistant diarylethene photochromic systems with a large structural flexibility.

Copper-promoted sandmeyer difluoromethylthiolation of aryl and heteroaryl diazonium salts

An efficient copper-promoted difluoromethylthiolation of aryl and heteroaryl diazonium salts is described. The reaction is conducted under mild reaction conditions and various functional groups were compatible. In addition, reactions of heteroaryl diazonium salts such as pyridyl, quinolinyl, benzothiazolyl, thiophenyl, carbazolyl, and pyrazolyl diazonium salts occurred smoothly to afford the medicinally important difluoromethylthiolated heteroarenes. Furthermore, a more practical one-pot direct diazotization and difluoromethylthiolation protocol was developed, and it converts the aniline derivatives into difluoromethylthiolated arenes. The utility of the method is demonstrated by difluoromethylthiolation of a number of natural products and drug molecules. A dose of salt: The title reaction is conducted under mild reaction conditions and various functional groups are compatible. (Hetero)aryl diazonium salts reacted smoothly to afford the medicinally important difluoromethylthiolated (hetero)arenes.

On the persistence of mouse urine odour to human observers: a review

To the human nose, mice produce unique, persistent and potent odour which is widely assumed to be derived mainly from their urine. In this review, we discuss why the mouse odour is so potent and long-lasting to the human nose. Sensory and chemical analyses have revealed that 2-sec-butyl-4,5-dihydrothiazole (SBT) was the major mousy odorant and present almost exclusively in male urine. It is not depleted from urine even after repeated headspace or solvent extractions since its majority is tightly bound to the major urinary proteins (MUPs) in male mouse urine that serve to control the release. The urinary concentration of SBT is estimated to be around several hundred parts per million when the binding of SBT to MUPs is considered, while its human olfactory threshold is estimated to be approximately at the parts per billion level. Therefore, the strikingly persistent quality of mouse urine odour, mainly contributed by SBT, is explained by its low human olfactory threshold, its presence in urine at a high concentration, and its delayed release by MUPs.
