New CF2-containing building blocks, ethyl 3-ethoxy-2,2-difluoro-3-hydroxy-propionate and -propioamide, were prepared via formylation of α,α-difluorinated Reformatsky reagents, and reacted with active methylene compounds, nitromethane or phosphonoacetate to afford α,α-difluoro-functionalized esters and amides.
通过α,α-二氟 Reformatsky 试剂的甲酰化反应,制备出了新的含 CF2 结构单元--3-乙氧基-2,2-二氟-3-羟基丙酸乙酯和丙酰胺,并与活性亚甲基化合物、硝基甲烷或膦酰乙酸酯反应,制备出了α,α-二氟官能化酯和酰胺。
