Reactivity of Carbamoyl Radicals. A New, General, Convenient Free-Radical Synthesis of Isocyanates from Monoamides of Oxalic Acid
摘要:
A new, general, simple synthesis of isocyanates was developed by oxidation of monoamides of oxalic acid with peroxydisulfate catalyzed by Ag and Cu salts. The reaction was carried out in a two-phase system (water and an organic solvent), and it is suitable also for practical applications, due to the simple experimental conditions and the inexpensive as well as nontoxic reagents. The first example of homolytic intramolecular aromatic carbamoylation is also reported.

A novel class of hydroxylases is described having the amino acid sequence of SEQ ID NO: 2, 4, 6 and 8, and variants and fragments thereof having HIF hydroxylation activity. The polypeptides of the invention have in particular prolyl hydroxylase activity. An assay method monitors the interaction of the HIF hydroxylase with a substrate. Modulators of HIF hydroxylase are provided for use in the treatment of a condition associated with increased or decreased HIF levels or activity or for the treatment of a condition where it is desirable to modulate HIF levels or activity.

New N,N-di-alkyl- or alkenyl-substituted derivatives of oxamic acid of which the two alkyl or alkenyl groups are different from each other are now produced and found to exhibit the cerebral protective effect against cerebral anoxia in brain of a mammalian animal, including human, and to be useful as an agent for improving or ameliorating the damaged or disturbed functions of the brain. Some known N,N-di-alkyl-substituted derivatives of oxamic acid of which the two alkyl groups are identical to each other are now also found to have similar, cerebral protective effect against cerebral anoxia and to be useful as an agent for improving the damaged functions of the brain.
