Fluoroalkyl-containing lithium 1,3-diketonates in reactions with amines and ammonium salts

Reactions of fluoroalkyl-containing lithium 1,3-diketonates with amines or ammonium salts in glacial acetic acid or methanol at 20 degrees C provide an efficient synthetic route to fluoroalkyl-containing beta-aminovinyl ketones. Depending on the conditions, reactions of lithium diketonates with 1-am...

Summary:Reactions of fluoroalkyl-containing lithium 1,3-diketonates with amines or ammonium salts in glacial acetic acid or methanol at 20 degrees C provide an efficient synthetic route to fluoroalkyl-containing beta-aminovinyl ketones. Depending on the conditions, reactions of lithium diketonates with 1-aminonaphthalene lead to formation of both beta-aminovinyl ketones and cyclocondensation products, benzo[h]quinolines. The latter can be obtained in one step without isolation of beta-aminovinyl ketones.
