An efficient reductive cyclization strategy was employed for the synthesis of N‐substituted β,γ‐dihydroxy‐γ‐lactams. A subsequent Petasis‐like reaction (PLR) through nucleophilic additions of boronic acids to intermediate N‐acyliminium ions produced substituted γ‐lactams. Overall, the application of this protocol provides β,γ‐dihydroxy‐γ‐lactams and functionalized γ‐lactams with potential interest for synthetic and bioorganic chemistry.
