Abstract: An atom-economical direct synthesis of carbazoles having aryl and aryl ketone groups has been achieved through Pd(II)-catalyzed cascade reactions between 1-(indol-2-yl)but-3-yn-1-ols and aldehydes. The reaction proceeds through alkyne-carbonyl metathesis, an uncommon pathway using palladium catalysts,… read more here.
