DIazo transfer reaction onto γ-butyrolactams (activated by α-ethyloxalylation) gave rare α-diazo γ-butyrolactams. Decomposition of the latter by Rh2(OAc)4 in the presence of alcohols and water gave products of O–H insertion of the respective metal-cabene species. Silver triflate (1 mol-%) was found to convert the γ-butyrolactams investigated into 1,5-dihydro-2H-pyrrol-2-ones which represent versatile building blocks. Particular instability was noted for α-diazo γ-butyrolactams bearing alkyl or o-substituted aryl substituents on the nitrogen atom. These were found to dimerize in solution or upon storage at room temperature to give fully conjugated bis-hydrazones along with the loss of a nitrogen molecule.

The aerobic oxidation of pyrrolones catalyzed by Fe(OTf)3 to form reactive N-acyliminium ion intermediates that undergo nucleophilic additions with alcohols to give the corresponding products in moderate to good yields is described.

Novel regioselective ring closing ene-yne metathesis provided an efficient access to different substituted 1-benzazepine scaffolds. The reported synthetic approach could also be used as a powerful tool for the selective formation of a highly functionaliza

A new route to N-aryl 2-alkenamides, N-allyl N-aryl 2-alkenamides, and N-aryl α,β-unsaturated γ-lactams from N-aryl 3-(phenylsulfonyl)propanamides

A series of N-aryl 2-alkenamides were produced efficiently by treating N-aryl 3-(phenylsulfonyl)-propanamides with potassium tert-butoxide in THF at 0°C. Without isolation, it was further treated with an additional equivalent of potassium tert-butoxide and allyl bromide to give N-allyl N-aryl 2-alkenamides in one pot in good yields. Followed by a ring-closing metathesis reaction, these N-allyl N-aryl 2-alkenamides were respectively converted into corresponding N-aryl α,β-unsaturated γ-lactams in moderate yields.
