Rhodium-catalyzed enantioselective desymmetrization of bicyclic hydrazines with alkynylboronic esters.
The first successful asymmetric transfer of rhodium-alkynyl species to symmetrical strained alkenes has been realized starting from bicyclic hydrazines and alkynylboronic esters.

متن کاملMajor mechanistic differences between the reactions of hydroxylamine with phosphate di- and tri-esters.
Hydroxylamine reacts as an oxygen nucleophile, most likely via its ammonia oxide tautomer, towards both phosphate di- and triesters of 2-hydroxypyridine. But the reactions are very different. The product of the two-step reaction with the triester TPP is trapped by the NH2OH present in solution to generate diimide, identified from its expected disproportionation and trapping products. The reacti...
متن کاملMetabolism of Hexose Phosphate Esters
Shortly after the discovery of insulin, it was shown by a number of investigators (Wigglesworth, Woodrow, Smith & Winter, 1923; Harrop & Benedict, 1924; Bollinger & Hartman, 1925) that there was a decrease in the inorganic phosphorus content of the blood in normal and diabetic animals following the injection ofinsulin. These observations first led to the hypothesis that insulin was concerned wi...
متن کاملHydrolytic Reactions of Esters and
The hydrolytic reactions of esters and amides of thiosulphurous acid ate investigated in a homogeneous medium. The esters are hydrolysed by alkali to gire sulphide, sulphite and thiosulphate whereas the amides are resistant towards alkali. Both the esters and amides are hydrolysed by acids giving hydrogen sulphide, sulphur dioxide, polythionates and elemental sulphur. The hydrolysis of these es...
