Syntheses of 2,2-dimethylchromene-5,8-quinone, 2,2-dimethylchromene-6,7-quinone, and 6,7-dimethoxy-2,2-dimethylchromene-5,8-quinone are described. Being easily bioreducible to electron-rich chromenes these compounds, and their oxirane derivatives, are of interest as possible anti-tumour alkylating agents.
