Abstract
Cycloadditions of phosphate dienes and quinones can be used to generate aromatic phosphates. Diethyl 3-methoxy-1-methylene-2-propenyl phosphate shows reactivity, stability, and regioselectivity comparable to the corresponding silyloxy diene. Because the phosphate ester in the product originates in the diene, cycloadditions with quinones will place this ester regiospecifically in the B-ring and allow facile distinction between the B- and A-ring oxygens of the cycloadduct.
