In basic, protic medium, the exocyclic migration of the double bond in esters of 2-methoxymethyl 3-alkyl 2-cyclopropenecarboxylic acids is highly regioselective, yielding only 2-methoxymethyl 3-alkylidene cyclopropanecarboxylic acids.The reaction is, in addition, stereospecific, leading to the trans isomer as the sole product.The exocyclic migration of the double bond appears to be irreversible and therefore the formation of enol ethers is not observed.
