Copper-Catalyzed Synthesis of α-Amino Imides from Tertiary Amines: Ugi-Type Three-Component Assemblies Involving Direct Functionalization of sp<sup>3</sup> C−Hs Adjacent to Nitrogen Atoms
from tertiary amines through copper-catalyzed three-component reactions involving the direct functionalization of sp3 C−Hs adjacent to nitrogen atoms. This reaction has demonstrated a tolerance to a wide range of functionalizations and can be performed under very mild conditions. A plausible mechanism has been proposed in which an Ugi-type cascadeassembly has been included.
Oxidative three-component reactions for the direct synthesis of α-amino amides and imides from tertiary amines have been developed. These reactions involve the functionalization of C(sp3)–H bonds adjacent to nitrogen atoms via mild aerobicoxidationusingvisiblelightphotoredoxcatalysis. The protocols are applicable to a wide range of amines and isocyanides, as well as water and carboxylic acids
The direct photoexcitation of isocyanides is able to trigger a collection of Ugi-like multicomponent reactions under metal-free conditions and in the absence of any additives starting from both linear and cyclic tertiary aromatic amines.
