Two synthetic routes to 3 -deoxy-3 -azido nucleosides are described, one toward the synthesis of 3'-deoxy-3-azidouridine and a second toward 3-deoxy-3'-azidocytidine. The target compounds may serve as precursors to provide building blocks for use in a . . .

Reported is an efficient synthesis of adenyl and uridyl 5'- tetrachlorophthalimido-5'-deoxyribonucleosides, and guanylyl 5'-azido-5'-deoxyribonucleosides, which are useful in solid-phase synthesis of phosphoramidate and ribonucleic guanidine oligo . . .

Synthetic routes to 5'-azidoribonucleosides are reported for adenosine, cytidine, guanosine, and uridine, resulting in a widely applicable one-pot methodology for the synthesis of these and related compounds. The target compounds are appropriate as . . .

The Corey-Bakshi-Shibata (CBS) catalyst provides an efficient mechanism to reduce ketones and achieve desired enantiopure alcohols. Herein, the diastereoselective reduction of C-2‘ and C-3‘-keto ribofuranoside derivatives to the corresponding arab . . .

Replacing the phosphodiester backbone of RNA with positively charged guanidinium linkages has been shown to enable RNA oligomers to overcome electrostatic repulsion and bind double-stranded DNA in a triplex with high affinity. Ribonucleotide monomers . . .

The membrane protein Anabaena Sensory Rhodopsin (ASR) is a prokaryotic retinal containing photoactive protein, from Anabaena sp. PCC 7120, undergoes a conformational change upon absorption of light. This causes the release of an associated so-called t . . .

One major contemporary environmental issues is the pollution of heavy metals into waterways. However, removal of heavy metal ions via bioremediation may be a possible solution. Using modified C. vibrioides paracrystalline RsaA surface layer proteins ( . . .

Structures and energies of complexes of dimethyl sulfide (DMS) with hydroxyl (OH) and hydroperoxyl (HO2) radicals have been studied using ab initio and density functional theory. Two isomers of the complex between OH and DMS were found, one dipole-dip . . .

The broad absorption of Cl3 radical was observed between 1150 and 1350 nm using cavity ring-down spectroscopy at 213–265 K and 50–200 Torr with He, N2, Ar, or SF6 diluents. The absorption intensity of Cl3 increased at lower temperature and higher pres . . .

Buffer-gas pressure broadening for the (0 00 3) ← (0 00 0) band of N2O was investigated with continuous-wave cavity ring-down spectroscopy within the temperature range of 243–353 K. The measured absorption profiles were analyzed with Voigt functions. . . .
