The kinetics of the thermolysis of 5′-deoxyadenosylcobalamin (AdoCbl, coenzyme B12) in
aqueous solution, pH 7.5, have been studied in the temperature range 30–85° C using …

Palmer and Abeles7® reported that 4,, 5,-didehydro-5'-deoxyadenosine (5) is converted to
both adenosine and SAH by SAH hydrolase, presumably via ketone 2. This observation led …

Inosinic acid was the first nucleotide obtained from nature and was reported by von Liebig in
1847. This was followed by the isolation of the first nucleoside, guanosine, by E. Schulze …

Ever since an optically active enantiomeric selenoxide was obtained for the first time by
Davis and co-workers in 1983, 1, 2 there have been several reports on the isolation of …

Various optically active areneseleninic acids (ArSeO2H; Ar= 4-Me-C6H4; 4-MeO-C6H4; 2-
MeO-C6H4; 2-MeOCO-C6H4; 2, 4, 6-Me3-C6H2; 2, 4, 6-Et3-C6H2; 2, 4, 6-iPr3-C6H2; 2, 4, 6 …

The reaction of olefins with pyridine-2-selenenyl bromide in methanol as solvent affords β-
methoxyalkyl 2-pyridyl selenides (A) in good to excellent yields. This reaction also proceeds …

the sole product when Y= OH, OR, OAc, and NHCOCH3, while a vinylic compound [\C=--C
(Y)—C—] was the main or the sole product when Y= CN, COR, CO2R, C= C, CC, NCS, NO2 …

The synthesis and stereochemistry of tricoordinated optically active selenium and tellurium
compounds are described. Telluronium salts, telluronium imides, and seleninic acids were …

Selenonium imides 1 and 2, stabilized by intramolecular coordination of the amino group of
8-dimethylamino-1-naphthyl substituent to the selenium atom, were synthesized. Optically …

Some optically active tricoordinate selenium and tellurium compounds, such as selenonium
ylide, telluronium ylide, selenonium imide, selenonium salt, telluronium salt, and telluroxide …
