A method for the synthesis of amide‐containing molecules was developed using vinylazides as an enamine‐type nucleophile towards carbon electrophiles, such as imines, aldehydes, and carbocations that were generated from alcohols in the presence of BF3⋅OEt2. After nucleophilic attack of the vinylazide, a substituent of the resulting iminodiazonium ion intermediate migrates to form a nitrilium ion,
Mn(III)-mediated formal [3+3]-annulation has been developed using readily available vinylazides and cyclopropanols with a wide range of substituents. Vinylazides were successfully applied as a three-atom unit including one nitrogen to prepare pyridines and δ-lactams by the reactions with monocyclic cyclopropanols as well as to construct 2-azabicyclo[3.3.1] and 2-azabicyclo[4.3.1] frameworks with
Polysubstituted N-H pyrroles with a wide variety of substituents were prepared from vinyl azides and 1,3-dicarbonyl compounds by using Mn(III) complexes as catalysts.
and functional materials, owing to its unique properties such as electron‐withdrawing character, metabolic stability, and lipophilicity. Described herein is the PhI(OAc)2‐mediated radicaltrifluoromethylation of vinylazides with Me3SiCF3 to efficiently generate α‐trifluoromethyl azines. The resulting α‐trifluoromethyl azines were successfully transformed to valuable fluorine‐containing molecules such
