## Abstract The reaction of electron‐deficient cyclopropane derivatives, __cis__‐1‐methoxycarbonyl‐2‐aryl‐6,6‐dimethyl‐5,7‐dioxospiro[2,5]octa‐4,8‐diones with benzoylmethylenetriphenylarsorane (**2**) and methoxycarbonylmethylene‐triphenylarsorane (**4**) was found to form __cis,trans__‐1‐methoxyca
