Abstract
Abstract Mild and general alumina-promoted hydrolysis conditions for converting α- iminonitriles into carboxamides have been developed. In combination with the oxidative three-component Strecker reaction, the one-pot direct amidation of aldehydes and alcohols is reported. Subsequently, an Yb (OTf) 3-catalyzed Michael addition of thiols to α, β- unsaturated α-iminonitriles is reported for the synthesis of β-mercapto-α-iminonitriles. The ...
