A novel, efficient, and mild synthetic route for the preparation of 2-aminopyridines via ruthenium-mediated [2 + 2 + 2] cycloaddition of α,ω-diynes and cyanamides has been developed. This atom-economical catalytic process demonstrated remarkable regioselectivities to access pyridine derivatives of high synthetic utility.

Synthesis of Benzo[<i>c</i>][2,7]naphthyridinones and Benzo[<i>c</i>][2,6]naphthyridinones via Ruthenium-Catalyzed [2+2+2] Cycloaddition between 1,7-Diynes and Cyanamides
A convenient method for the ruthenium-catalyzed synthesis of benzo[c]naphthyridinone derivatives is reported. The [2+2+2] cycloaddition from various mono- and disubstituted 1,7-diynes and cyanamides provided benzo[c][2,7]naphthyridinones as major products and benzo[c][2,6]naphthyridinones as minor ones in yields of ≤79% and regioselectivities of ≤99:1. This method is amenable to internal and terminal
报道了一种简便的钌催化合成苯并[ c ]萘啶酮衍生物的方法。各种单取代和双取代的 1,7-二炔和单氰胺的 [2+2+2] 环加成反应提供苯并[ c ][2,7]萘啶酮作为主要产物,苯并[ c ][2,6]萘啶酮作为次要产物产率≤79%,区域选择性≤99:1。该方法适用于内部和末端二炔以及许多具有不同官能团耐受性的氰胺。
