A concise two-step procedure for the synthesis of novel δ-lactam tetrazoles has been established via the Ugi-azide reaction using 5-oxohexanoic acid along with primary amines, isocyanides, and azidotrimethylsilane followed by 1,1′-carbonyldiimidazole-mediated intramolecular amide formation. Expansion to ε-lactam tetrazole scaffolds was accomplished using methyl 6-oxoheptanoate via the same Ugi-azide reaction followed by basic hydrolysis and SOCl2 activation to enable lactam formation.
