A library of 2-substituted quinolines was synthesized in solution from mixt
ures of Grignard reagents and a quinolinium salt. Grignard reagents were pr
epared in one pot, taking advantage of the entrainment method for their pre
paration from unreactive alkyl halides. Then mixtures of 2-alkylquinolines
were readily accessible for biological tests or separated by centrifugal-pa
rtition chromatography (CPC) prior to the biological screening. (C) 2001 El
