摘要：

The Wittig reaction of 3-hydroxy-1,2,3,4-tetrahydroquinoline-2,4-diones 2 with ethyl (triphenylphosphoranylidene)acetate 3 proceeds stereoselectively to give E-4-carbethoxymethylene-1,2,3,4-tetrahydro-2-quinolones 4, which were hydrolyzed to corresponding acids 6. Butenolides 5 were detected end, in some cases, isolated as a minor product of the Wittig reaction.
