- 1-Arylideneamino-2,2,2-trichloroethanols as synthetic equivalents of arylideneimines in the reaction with cyclopropenone derivatives
-
1-Arylideneamino-2,2,2-trichloroethanols react regiospecifically with cyclopropenones to form 2,2′-diaryl-1,1′,2,2′-tetrahydro- 3′,3′H-2,2′-bipyrrole-3,3′-diones. A new preparative method was developed for the synthesis of 1-arylideneamino-2,2,2- trichlor

- Reaction of synthetic equivalents of arylideneimines, viz., 1-aryl- N,N'-bis(arylidene)methanediamines, with 2,3-diphenylcyclopropenone
-
N,N'-Bis(arylidene)methanediamines regiospecifically react with 2,3-diphenylcyclo- propenone to form stable adducts of both the mono- and the diaddition. Ammonium acetate serves as the catalyst of the process. During hydrolysis of these adducts, an oxidat

- Cycloaddition Reaction of Dimethyl Acetylenedicarboxylate with 2,4,5-Triphenyl-3H-pyrrol-3-one 1-Oxide
-
The reaction of 2,4,5-triphenyl-3H-pyrrol-3-one 1-oxide with dimethyl acetylenedicarboxylate gave pyridine 9a, 4(3H)-pyridone 10a, isoxazolidine 11, and traces of pyridone 13.Pyridone 10a is not an intermediate in the formation of 9a, yet on photolysis or pyrolysis above its melting point, 10a yielded pyridine 9a.Possible reaction mechanisms that rationalize the formation of these products are discussed.
