One-pot synthesis of organophosphate monoesters from alcohols
摘要:
A one-pot procedure for the phosphorylation of alcohols provides the corresponding phosphate monoesters in improved yields. The protocol features the use of tetrabutylammonium hydrogen phosphate and trichloroacetonitrile, followed by purification of the crude product by flash chromatography on silica gel. The final step, cation exchange chromatography, affords the organophosphates as ammonium salts that are usually required for biochemical applications. The mechanism appears to be phosphate rather than alcohol activation by trichloroacetonitrile. (c) 2013 Elsevier Ltd. All rights reserved.
The present invention provides novel methods for determining the presence or amount of a hydrolytic enzyme in a sample, based on novel substrates for the enzymes, and also provides compositions and methods that provide highly sensitive assay methods for such hydrolytic enzymes.
