The reaction of [(benzyloxy)methylene]cyclopropane (I) with alkylidenemalononitriles at ambient pressure afforded the corresponding spiro cyclobutane derivatives in good to high yields. For example, the reaction of I with benzylidenemalononitrile, [(2-naphthyl)methylene]malononitrile, and (tert-butylmethylene)malononitrile in acetonitrile at 80 °C gave the corresponding spiro[2.3]hexanes in 96, 96, and 91% yields, resp. Control experiments proved that the reaction proceeds via a well-stabilized zwitterionic intermediate.
