Reaction of cyclic meso allylic diacetates 5 and 6 with various 2-aminophenols, benzene-1,2-diamine, and benzene-1,2-diol in the presence of a palladium-phosphine catalyst gave novel phenoxazine, phenazine, and dioxine derivatives 7, 11, and 12 in moderate to excellent yields.
在钯-膦催化剂存在下,环状内消旋烯丙基二乙酸酯 5 和 6 与各种 2-氨基苯酚、苯-1,2-二胺和苯-1,2-二醇反应生成新型吩恶嗪、吩嗪和二恶英衍生物 7 、11 和 12 的产量适中至极好。
