Highly acidic carbo and heterocyclic β-dicarbonyl compounds such as barbituric acid, 3,5-dimethyl-2-1,2,6-thiadiazine 1,1-dioxide, cyclohexane-1,3-dione, tetronic acids, Meldrum acid and 1,2-diphenylpyrazolidine-3,5-dione are efficiently C-allylated with primary and secondary allylating agents under palladium catalysis.
高酸性碳和杂环β-二羰基化合物,例如巴比妥酸,3,5-二甲基-2 -1,2,6-噻二嗪1,1-二氧化物,环己烷-1,3-二酮,四氢代酸,Meldrum酸和1在钯催化下,用伯和仲烯丙基化剂有效地将2--二苯基吡唑烷-3,5-二酮进行C-烯丙基化。
