from β-keto α-diazo carbonylcompound to ketones or α,β-unsaturatedcompounds were subjected to Rh2(OAc)4-catalyzed and photo-induced diazo decomposition. The Rh2(OAc)4-catalyzed reaction afforded intramolecular O–H insertion products, while the photo-induced reaction gave Wolff rearrangement/intramolecular nucleophilic addition products. The transformations represent new approaches to tetrahydrofuran
