A novel rearrangement sequence of 3-hydroxyazetidines via a Ritter initiated cascade provides highly substituted 2-oxazolines in high yields. The reaction conditions and substrate scope of the transformation have been studied demonstrating the generality of the process. The derived products can also be functionalized in order to undergo further intramolecular cyclization leading to a new class of macrocycle

selective C–N bond oxidative cleavage method to 3-acylated indoles by Pd-catalyzed oxidative cross coupling of indoles with α-aminocarbonylcompounds has been developed; moreover, one-pot synthesis of 3-acylated indoles from 2-ethynylanilines and α-aminocarbonylcompounds has also been established. Importantly, the products 3-acylated indoles can be used to construct polyheterocyclic compound, which can
A protocol for the copper-catalyzed oxidative self-coupling of α-amino carbonylcompounds has been developed for the synthesis of tetrasubstituted 1,4-enediones (Z-isomers) in moderate to good yields through the cleavage of four sp3C–H bonds and the simultaneous formation of one C=C double bond in the α-amino carbonylcompound. The strategy has the advantages of using readily available starting materials
Cu(OAc)2 and acids promoted the oxidative cleavage of α-aminocarbonyl compounds with amines: efficient and selective synthesis of 2-t-amino-2-imino-carbonyl and 2-amino-2-oxocarbonyl
method for the synthesis of 2-t-amino-2-imino-carbonyl (C) and 2-amino-2-oxocarbonyl (D) compounds has been discovered through a copper-promoted oxidating amidation reactions between α-amino -carbonyl compounds and amines. Promoted by the crucial copper species, perfect selectivity and good to excellent yields could be achieved. This transformation is achieved through CN bond oxidative cleavage and formation
