Cyclofunctionalisation of unsaturated acids with benzeneselenenyl chloride. Kinetic and thermodynamic aspects of the rules for ring closure

Article abstract of DOI:10.1016/0040-4020(80)85054-X

Experimental procedures are described for the synthetically useful reaction by which olefinic acids are converted into lactones carrying a benzeneseleno-group. Data are presented to define some of the mechanistic details of this type of cyclofunctionalisation and kinetic and thermodynamic factors relevant to the Rules for Ring Closure are discussed. A nomenclature is introduced for a treatment of ring-fusion stereochemistry.
