资源简介：
Substituted cyclopentadienone acetals (CPDAs) were synthesized by a thermal or palladium-catalyzed [3 + 2] cycloaddition reaction of a substituted cyclopropenone acetal to an electron-deficient acetylene. The synthesis afforded di-, tri-, and tetrasubstituted CPDAs of considerable structural varieties that undergo Diels−Alder reaction to produce bicyclo[2.2.1]heptenes.
