摘要：

Diethyl 2,5-dimethylcyclphept-4-ene-1,1-dicarboxylate has been synthesised from ethyl 3-methyl-2-oxocyclo-pentane-1-carboxylate via a bicyclic tosyloxy-ketone intermediate. Only one of the ester functions is hydrolysed by alkali and the resulting half-ester has been converted into the title ketone. A new fragmentation reaction of an axial tosyloxy-ketone is reported.
