Watch out, the borrowers are about! N,N′-alkyl aryl ureas and N,N′-dialkyl ureas were synthesized by a transition metal-catalyzed regioselective N3-alkylation of the N-monosubstituted ureas with alcohols. This opens up the design of regioselective N-alkylation of amines with alcohols based on the regioselective condensation of amines with aldehydes, facilitating the progress of the “hydrogen autotransfer” (or “hydrogen-borrowing”)
