摘要

tert-Butoxyquinones were prepared from the thermal ring expansion of 4-alkynyl-, 4-alkenyl-, and 4-aryl-tert-butoxycyclobutenones and shown to be readily converted to hydroxyquinones upon treatment with tri-fluoroacetic acid at low temperature. This is a useful transformation since no reliable general route to hydroxyquinones has previously been available. The synthetic scope of this methodology as well as its specific utilization in ...
