A new electrochemical methodology has been developed for the generation of oxycarbonyl radicals under mild and green conditions from readily available hemioxalate salts. Mono- and multi-functionalised γ-butyrolactones were synthesised through exo-cyclisation of these oxycarbonyl radicals with an alkene, followed by the sp3 -sp3 capture of the newly formed carbon-centred radical. The synthesis of functionalised

The synthesis of morpholin‐3‐one and 1,4‐oxazepan‐3‐one skeletons was achieved by the cycloaddition reaction of alcohol‐tethered enones and α‐halohydroxamates. This process proceeds through the addition of the hydroxyl group in the enone to an in‐situ generated azaoxyallyl cation followed by intramolecular aza‐Michael‐type trapping. Morpholin‐3‐ones and 1,4‐oxazepan‐3‐ones could be generated from γ‐hydroxy

4-allyl-2-methylene-1,3-oxathiolan-5-ones through the 1,5-cyclization of a thiocarbonyl ylide intermediate followed by Claisen rearrangement with allene episulfide through the 1,3-cyclization of the intermediate. Other alkenyl and alkynyl diazoacetates also gave similar products through the thiocarbonyl ylide without affording its intramolecular 1,3-dipolar cycloadduct.
