Synthesis of Hydroxyquinones and Related Compounds: Semisquaric Acids, (+/-)-Terreic Acid, (+/-)-Perezone, and (+/-)-Isoperezone
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 trifluoroacetic 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 the synthesis of a semisquaric acid, and the natural products, (+/-)-terreic acid, (+/-)-perezone, and (+/-)-isoperezone, are described.
