Abstract
Abstract When reacted with different ketone enamines, in the presence of magnesium bromide, 1-methoxycarbonyl- and 1-cyano-cyclobutene lead to α-cyclobutyl ketones or to amino-bicyclo [2.2.0] hexane adducts. These products are not formed competitively, but apparently result from different reactions. The cyclobutene nitrile undergoes an exclusive cycloaddition reaction with morpholino enamines. All other reagent combinations lead solely to cyclobutyl ketones. Some reactions of the cycloadducts, among them the thermolysis, were investigated.
