A simple procedure for preparing annulated p-benzoquinones. An improved synthesis of 1, 4-dihydro-1, 4-methanonaph-thalene-5, 8-dione

A simple and efficient two-step, one-pot synthesis of substituted 1, 4-dihydro-1, 4-methanonaphthalene-5, 8-diones is reported. This synthesis, which utilizes readily available starting materials and inexpensive reagents, can be used to prepare la-lc in 70-90% overall yield. This procedure was extended successfully to prepare a more highly complex annulated p-benzoquinone i.e., 8.
