The present invention relates to compounds that have CYP
450
inhibiting properties and are therefore useful as boosters of certain drugs, i.e. they are able to increase at least one of the pharmacokinetic variables of certain drugs when co-administered. The invention further provides the use of said compounds as improvers of the bioavailability of certain drugs. Methods for the preparation of the compounds of the invention and pharmaceutical compositions are also provided.

Efficient Condensation between
Glyoxal Hydrates and Sulfonium Salts Leading to Highly
Functionalized 1,4-Diketones
作者:Chunbao Li、Qiyun Shao
DOI:10.1055/s-2008-1078267
日期:——
α-Alkylthio-substituted α,β-unsaturated 1,4-dicarbonyl compounds with three different functionalities are easily available through condensation of sulfonium salts and various aromatic or aliphatic glyoxal hydrates catalyzed by Na2SeO3 or a combination of selenium dioxide and Na2CO3.
