Аннотация

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