Spirocyclic 1,2,3,4-tetrahydroquinoline derivatives were prepared in quantitative yield by three-component condensation of dimedone or Meldrum’s acid with formaldehyde and (1S,3R,4S)-1,7,7-trimethyl-3(arylamino)bicyclo[2.2.1]heptan-2-one or (1S,2S,3R,4S)-1,7,7-trimethyl-3-(arylamino)bicyclo[2.2.1]heptan2-ol.
通过将二甲基酮或梅尔杜姆酸与甲醛和(1S,3R,4S)-1,7,7-三甲基-3-(芳基氨基)双环[2.2.1]heptan-2-one or (1S,2S,3R,4S)-1,7,7-trimethyl-3-(arylamino)bicyclo[2.2.1]heptan2-ol.
