Abstract
Diethyl, 2,5-dimethylcyclohept-4-ene-1.1-dicarboxylate has been synthesised from ethyl 3-methyl-2-oxocyclopentane-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.
