  Synthesis and properties of dihydrocyclobuta[e]pyrene and tetrahydrodicyclobuta[e,l]pyrene

  摘要：

  Dihydrocyclobuta[e]pyrene and tetrahydrodicyclobuta[e,l]pyrene were prepared by the sequence of photo-cycloaddition of stryene derivatives, transannulation, and aromatization through lithiation. They reacted with dienophiles at 180-degrees-C to afford Diels-Alder adducts in excellent yields.
