These precursors are easily accessible from aryl methyl ketones. Various functional groups like alkyl, aryl, nitrile, amine, aroyl and thiomethyl can be directly installed to the benzene ring. The one-pot approach for the construction of thiomethylated-benzene nucleus was also developed. The structure of the synthesized compound was confirmed by X-ray crystallography.
已从芳基/杂芳基/环丙基甲基酮建立了碱促进的各种官能化硫代甲基化苯的战略合成。通过3,3-双(甲硫基)-1-芳基丙-2-烯-1-酮与2-(1-芳基/环丙基)亚乙基的反应,我们可以直接访问嵌入有不同官能团的硫代甲基化苯核氢化钠存在下于THF中在回流温度下制备丙二腈。这些前体很容易从芳基甲基酮获得。可以将各种官能团如烷基,芳基,腈,胺,芳酰基和硫代甲基直接安装在苯环上。还开发了一种一锅法构建硫代甲基化苯核。通过X射线晶体学确认合成的化合物的结构。
