Abstract
A number of 1- and 1,2-disubstituted cyclopropenes undergo [4+2]-cycloaddit ion to methyl vinyl ketone or acrolein at ambient temperature to produce 2- oxabicyclo[4.1.0]hept-3-enes. When 1-phenyl-2-trimethylsilyl cyclopropene i s treated with 0.4 mel. equiv. of m-chloroperbenzoic acid, the derived ring -opened enone undergoes [4+2]-cycloaddition to the remaining starting mater ial at ambient temperature.
