decarboxylation mechanism is preliminarily revealed. This protocol features metal-free reaction conditions and operational simplicity, allowing the lactamization of 2-vinylanilinesusing a readily accessible carbonyl source and the synthesis of various 2-quinolinones with excellent chemoselectivity at room temperature.
The first direct use of carbon dioxide in the lactamization of alkenyl and heteroaryl C−H bonds to synthesize important 2‐quinolinones and polyheterocycles in moderate to excellent yields is reported. Carbon dioxide, a nontoxic, inexpensive, and readily available greenhouse gas, acts as an ideal carbonyl source. Importantly, this transition‐metal‐free and redox‐neutral process is eco‐friendly and desirable
Transition-metal-catalyzed hydroformylation has become an essential tool for the synthesis of aldehydes. In this paper, we highlight several examples of synthetically useful applications of homogeneous and heterogeneous rhodium-catalyzed hydroformylation, as well as several examples of tandem processes involving hydroformylation as a reaction step developed in our laboratory.
An efficient palladium-catalyzed intermolecular oxidativecyclization of 2-vinylanilines with isocyanides to the synthesis of 2-aminoquinolines is achieved. This transformation is applicable to a broad range of 2-vinylanilines and isocyanides.
