Abstract
Summary: A general route to a wide variety of substituted quinones (furyl, indolo, pyrrolo, quinolino, naphtho, and anthra) has been developed via the thermolysis (160 OC, xylene) and subsequent oxidation (air or Ce4+) of 4-hydroxy-4-substituted-cyclobutenones (eq 1) and 2-hydroxy-2-substituted-benzocyclobutenones which were formed by the regioselective addition of an appropriate aryl or heteroaryl (etc.) lithium reagent to the corresponding ...
