Green approach for the conversion of olefins into vic-halohydrins using N-halosuccinimides in ionic liquids
摘要:
Alkenes undergo smooth bromo- and iodohydroxylation with N-bromo- and N-iodosuccinimides/water, respectively, using the air and moisture stable ionic liquid [bmim]BF4 as a novel recyclable reaction medium in high to quantitative yields. N-Halosuccinimides show enhanced reactivity in ionic liquids thereby reducing the reaction times and improving the yields considerably. (c) 2005 Published by Elsevier Ltd.

Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds to treat or prevent diseases or disorders associated with a defect in glyoxylate metabolism, for example a disease or disorder associated with the enzyme glycolate oxidase (GO) or alterations in oxalate metabolism. Such diseases or disorders include, for example, disorders of glyoxylate metabolism, including primary hyperoxaluria, that are associated with production of excessive amounts of oxalate.

The iodomethylation of carbonyl compounds giving iodohydrins has been achieved under ordinary conditions by the use of diiodomethane and samarium. A novel synthesis of cyclopropanols from α-haloketones or 1,2-dibenzoylethane is also described.
