摘要

The mono-and diazanaphthoquinones underwent facile cycloaddition with cyclic and alicyclic dienes, and in the majority of these cycloadditions the initial 1: l-cycloadducts or their tautomers and intermediate products formed in the oxidation procedure leading to the final azaanthraquinones were isolated. Quinoline-5, 8-dione and l-methoxy-l, 3- cyclohexadiene gave the 8-methoxy isomer in an essentially regiospecific cycloaddition; ...
