    Synthetic Approach to Benzocyclobutenones Using Visible Light and a Phosphonate Auxiliary
    摘要:
    Reported herein is a two-step procedure to synthesize benzocyclobutenones from (o-alkylbenzoyl)-phosphonates. It consists of a visible-light-driven cyclization reaction forming phosphonate-substituted benzocyclobutenols and subsequent elimination reaction of the H-phosphonate, which assumes a key role as the recyclable auxiliary. A wide variety of functionalized benzocyclobutenones, which include those difficult to synthesize by conventional methods, are efficiently synthesized.

    日期:2001.11
    rapid and total synthesis of a tricyclo[6.2.0.0]deca-1,5,7-triene-3,10-dione 7b is described. Its synthesis involves the [2+2] cycloaddition of a benzyne to 2-methylene-1,3-dioxepane followed by hydrolysis to the corresponding ketone. This reaction is totally regioselective and the real structure of the molecule is given thanks notably to the X-ray crystal structure of the intermediate benzo-bis-cyclobutene
