Introduction of alkyl groups on azodicarboxylate esters is an important method to prepare alkyl aminederivatives. Herein, we report reactions of 4-alkyl-1,4-dihydropyridines as alkylation reagents with di-tert-butyl azodicarboxylate to prepare alkyl aminederivatives under heating conditions. The alkylation reactions via C–C bond cleavage of the dihydropyridines are achieved in the absence of catalysts

cerium photocatalyzed radical decarboxylative hydrazination of carboxylic acids with di-tert-butylazodicarboxylate (DBAD). The operationally simple protocol provides rapid access to synthetically useful hydrazine derivatives and overcomes current scope limitations in the photoredox-catalyzed decarboxylation of carboxylic acids.
