摘要:
An efficient method for the synthesis of 2-ferrocenyl-substituted quinoline-4-carboxylic acids via the reaction of acetyl- and 1,1'-diacetylferrocene with isatin under the conditions of the Pfitzinger reaction was developed. Starting from the obtained acids methyl esters, amides, N-methyl-N-methoxyamides, and oximes (at one of the free acetyl groups) of some of these compounds were synthesized.
