[image omitted] Cyclopropyl cyanoesters 2 were reliably converted to -lactones 4 on treatment with aqueous sulfuric acid. The cyanoesters could be easily prepared from ketones or aldehydes in two steps, making this process particularly attractive from an efficiency standpoint.

2-Cyanocyclobutane alkylsilylacetals, obtained by a [2+2] cycloaddition reaction of ketene alkylsilylacetals and acrylonitrile, have allowed the synthesis of 2-cyanoclobutanones, 4-chloro-4-cyanobutanoates and 4-cyanobutanoates by respectively acidic catalysis, FeCl3 cleavage and nBu4NF treatment. The cycloadducts obtained from chloroketene alkylsilylacetals give 2-cyanocyclopropanecarboxylates by
