Abstract

[4 + 2] Cycloaddition reaction proceeds between N-aryl Schiffs bases and 1-alkenyl sulfides, a 1, 2-propadienyl sulfide, or 1-alkynyl sulfides in the presence of BF3·OEt2 to provide 2-substituted quinoline derivatives. A 2-alkyl-4-quinolone alkaloid, leptomerine, is prepared by applying the present cycloaddition reaction.
