Reaction of 2,2-Dichloro-1-methyl-3-phenylcyclopropanemethanol Tetrahydropyranyl Ether with Butyllithium / CO2 and Subsequent Reactions of the Products

While the title reaction starting from 2a followed by acidic work-up affords only the α-chlorolactone 1 with low yield, alcaline work-up and addition of dimethyl sulfate lead to a mixture of the esters 2b and c and the chlorocyclopropene 3a.From 2b/c with
