Several phenols were synthesized from dimethyl β,β′,δ,δ′-tetraoxoalkanedioates, which were prepared by the condensation of methyl acetoacetate dianion with N,N,N′,N′-tetramethylalkanediamides in the presence of BF3·OEt2.
在
BF3-OEt2 的存在下,通过
乙酰乙酸甲酯二酐与 N,N,N,N′,N′-四甲基烷二酰胺缩合制备了 β,β′,δ,δ′-四氧代烷二酸二甲酯,并从该二甲酯合成了多种
酚类化合物。
