procedure for the synthesis of highly functionalized N-heterocyclic 1,6-annulated 2-pyridones and 2,3-annulated 4-pyrimidinones has been elaborated through a gold-catalyzed tandem hydroamination/cycloisomerization cascade. This novel and highly efficient method allows the rapid construction of these diverse N-heterocyclic scaffolds starting from readily available building blocks, and shows a wide scope
通过金催化串联加氢胺化/环异构化级联,详细阐述了合成高度官能化的 N-杂环 1,6-环 2-吡啶酮和 2,3-环 4-嘧啶酮的简洁而灵活的程序。这种新颖且高效的方法允许从现成的构建块开始快速构建这些不同的 N-杂环支架,并显示出广泛的范围和良好的官能团耐受性。(±)-seco-antofine 和 (±)-septine 的全合成是采用这种策略实现的。
