A ruthenium-catalyzed functionalization of benzaldehyde substrate with organic azides promoted by various transient directing groups has been developed. In this approach, C-H amination is achieved via a transient aldimine intermediate in good to excellent yields.

An iridium-catalyzed ortho-C(sp2)-H amidation reaction of benzaldehydes with organic azides has been developed. A catalytic amount of 3,5-di(trifluoromethyl)aniline was used to promote the Ir-catalyzed directed C-H amination reaction through a transient aldimine intermediate. This reaction tolerates a broad scope of benzaldehyde substrates and works well with a range of aryl- and alkylsulfonyl azides.

Ir-catalyzed direct C-H sulfamidation of benzaldehydes has been achieved. A series of ortho-amided benzaldehydes were obtained in up to 95% yields for 21 examples with excellent regioselectivity and broad functional group tolerance. This transformation could proceed smoothly with low catalyst loading under external-oxidant-, acid-, or base-free conditions. Molecular nitrogen was released as the sole byproduct, providing an environmentally benign sulfamidation process.
Construction of divergent fused heterocycles via an acid-promoted intramolecular ipso-Friedel-Crafts alkylation of phenol derivatives

Two different cascade cyclization processes were developed using aryl group-substituted propargyl alcohol derivatives with a p-hydroxybenzylamine unit as common substrates. Using TFA as an acid promoter, an intramolecular ipso-Friedel-Crafts alkylation of
