A potentially general regiospecific synthesis of substituted quinones from dimethyl squarate
TL;DR: In this article, a potentially general regiospecific synthesis of benzo- and naphthoquinones is described, which starts with dimethyl squarate (1), which is converted to the cyclobutenone ketal 9 upon sequential treatment with an organolithium reagent and then BF 3 etherate or TFAA in THF/methanol.
