A highly regioselective Friedländer reaction mediated by lanthanum chloride
摘要:
A highly efficient and regioselective Friedlander reaction of unsymmetrical 1,3-diketones with 2-aminoaryl aldehydes (ketones) is described. The methodology leads to the synthesis of a broad scope of substituted quinolines in high yield and excellent regioselectivity. (C) 2012 Elsevier Ltd. All rights reserved.
