3-dicarboxylate and its two products of thermal rearrangement, methyl syn- and anti-2-carbomethoxycyclopropylideneacetate, has allowed the exclusion of a planar transition state and the construction of a unique mechanism in which the substituents at a pivotal atom remain perpendicular to the plane of the system of four atoms that constitute the methylenecyclopropane of starting material and product.
