- 論文の詳細を見る
Cycloaddition of some five-membered mesoionic compounds with dimethyl 7-tosyl-7-azabicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylate occurs only across the unsubstituted double bond. Pyrolysis of the adducts resulted in a double fragmentation reaction to give two five-membered aromatic heterocycles. A dithiolone adduct gave the <I>S</I>-oxide, which was pyrolyzed to the corresponding thiopyran-2-one.
