Se hela listan på cn.chem-station.com 2015-05-01 · The reaction proceeds via Catellani ortho C-H amination followed by decarboxylative alkynylative amination. Different terminal alkyne precursors were screened, and it was found that alkynyl carboxylic acids were superior over other alkynes, which led to operationally simple reaction conditions (no gradual addition of alkynes) and broad substrate scope. component Catellani reaction with remarkable regio- and chemose-lectivity by using readily available reagents. Highly and contiguously substituted arenes are useful building blocks for numerous applications in the prepara-tion of pharmaceuticals and in mate-rials.1 Therefore, much attention has been focused on their synthesis.
