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 new synthetic protocol has been developed for the synthesis of N‐formamide derivatives using ethers as a C1 synthon undermetal‐free reaction conditions. The reaction is proposed to proceed through C−H functionalization, C−O cleavage, and C−N bond formation. This protocol is applicable to a variety of primary amines resulting in N‐formamides in moderate to good yields. 1,4‐dioxane was chosen as best
