Synthesis of Cyclopropylamines through an Electro-Induced Hofmann Rearrangement

Abstract

AbstractA practical access to cyclopropylamines from the corresponding amides is disclosed, according to an electro-induced Hofmann rearrangement. In an undivided cell under galvanostatic conditions, a panel of cyclopropyl amides was readily converted into the corresponding amines (17 examples, 23% to 94% yield). This reaction allowed an easy access to the versatile cyclopropylamines and is complementary to the existing methods.
