Take the direct path: Sequential nucleophilic addition of N‐methoxyamides using DIBAL and organometallic reagents provided substituted N‐methoxyamines in one pot via five‐membered chelated intermediates (see scheme, DIBAL=diisobutylaluminum hydride). The reaction allows functionalization of acyclic amides and macrolactams without a preactivation step, which is generally required for inert amide carbonyl
