cross-coupling reaction between α-amino carbonylcompounds and azoles by copper catalysis using di-tert-butyl peroxide (DTBP) as an oxidant is described. A diverse range of azoles undergo the dehydrogenative imidoylation smoothly with various α-amino carbonylcompounds for the exclusive formation of the corresponding N-imidoyl azoles in high yields under air. The synthetic method has the advantages of good

A novel copper‐catalyzed oxidative alkylation of α‐amino carbonyl compounds with ethers has been established for the selective synthesis of α‐etherized α‐amino carbonyl compounds. This oxidative alkylation is achieved by dual C(sp3)H bond oxidative cross‐coupling, and its scope is expanded to α‐amino ketones, α‐amino esters and α‐amino amides.

A novel and efficient direct oxidative phosphonylation of α-amino ketones and α-amino acidderivatives with dialkyl phosphites by the catalysis of a cobalt salt under air is disclosed. A variety of α-amino ketones and α-amino acidderivatives underwent the reaction well with dialkyl phosphites to produce the desired α-aminophosphonates. This protocol not only provides an alternative synthetic route

An Fe(III)-catalyzed efficient method has been developed for the synthesis of selenoester derivatives in high yields through the coupling of α-amino carbonyl/glycine derivatives and diselenides under ambient air. A library of benzoselenoate derivatives having a variety of substituents has been synthesized. A plausible reaction pathway has been predicted. Experimental results suggest that the reaction
