Isocyanides are versatile building blocks, and have been extensively exploited in CH functionalization reactions. However, transition‐metal‐catalyzed direct CH functionalization reactions with isocyanides suffer from over‐insertion of isocyanides. Reported herein is a radical coupling/isomerization strategy for the cross‐coupling of isocyanides with activemethylenecompounds through silver‐catalysis
A novel iron-catalyzed aminolysis of beta-carbonyl 1,3-dithianes with various amines including ammonia, primary and secondary amines, as well as hydrazine hydrate has been developed, leading to the synthesis of steleodefined beta-enaminones and 3,4-disubstituted pyrazoles in good to high yields.
