N-Alkylation of anilines, carboxamides and several nitrogen heterocycles using CsF–Celite/alkyl halides/CH3CN combination
Safdar Hayat,Atta-ur-Rahman,M. Iqbal Choudhary,Khalid Mohammed Khan,Wilhelm Schumann,Ernst Bayer +5 more
TL;DR: In this article, it was shown that the N-alkylation of aniline, carboxamides and heterocyclic compounds bearing an acidic hydrogen atom attached to nitrogen can be accomplished with alkyl halides in acetonitrile and cesium fluoride-celite employed as a solid base.
Journal ArticleDOI
Synthesis, spectral and biological evaluation of some new thiazolidinones and thiazoles based on t-3-alkyl-r-2,c-6-diarylpiperidin-4-ones.
TL;DR: A stereospecific synthesis of some thiazolidinones and thiazoles was achieved conveniently through certain alpha-halo keto agents and reactivity of chloroacetyl chloride was successfully enhanced by CsF-Celite+CH(3)COONa.
