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
磷酸二烯和醌的环加成可用于产生芳族磷酸酯。3-甲氧基-1-亚甲基-2-丙烯基磷酸二乙酯显示出与相应的甲硅烷氧基二烯相当的反应性,稳定性和区域选择性。由于产物中的磷酸酯起源于二烯,因此与醌进行环加成反应会将这种酯区域特异性地置于B环中,从而可以轻松区分环加合物的B环和A环氧。
