摘要：

[4+2] Cycloaddition reaction proceeds between N-aryl Schiff's bases and I-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.
