High Yields

A fast and convenient protocol for the synthesis of novel spiro[dihydropyridine-oxindole] derivatives in satisfactory yields was developed by the three-component reactions of arylamine, isatin and cyclopentane-1,3-dione in acetic acid at room temperature. On the other hand the condensation of isatin with two equivalents of cyclopentane-1,3-dione gave 3,3-bis(2-hydroxy-5-oxo-cyclopent-1-enyl)oxindole in high yields. The reaction mechanism and substrate scope of this novel reaction is briefly discussed.

Aqueous Acid

1-Aminobarbituric acid undergoes a facile isomerization in aqueous acid to 2-(5-oxo-4,5-dihydro-lH-l,2,4-triazol-3-yl)acetic acid which in turn can be decarboxylated to give 3-methyl-1H-1,2,4- triazol-5(4H)-one. The isomerization reaction is shown to be a general one, adaptable to the synthesis of oxotriazolyl aliphatic acids and their decarboxylated products. A reaction mechanism for the isomerization is proposed.

Induced Decomposition

The CO2 cw laser powered homogeneous pyrolysis (LPHP) of acetone, 2,3-butanedione and cyclobutanone (all 1.3 - 4kPa) sensitized by sulphur hexafluoride (0.7-1.3kPa) was investigated. The decomposition course of the ketones is analogous to that occuring under conventional pyrolytic conditions. The decomposition rate and the product composition are affected by laser power, partial pressure of the sensitizer, and the buffer gas (helium) added. Besiedes the conventional pyrolytic products, the LPHP of acetone and 2,3-butanedione affords acetylene and that of cyclobutanone produces acetic acid. A possible reaction mechanism of the decompositions is discussed.
