New Synthesis of Jasmine Lactone and Related δ-Lactones from 1,2-Cyclohexanedione. Preparation and Dye-Sensitized Photooxygenation of 3-(2-Alkenyl)- and 3-(2-Alkynyl)-1,2-cyclohexanediones
NEW SYNTHESIS OF JASMINE LACTONE AND RELATED δ-LACTONES FROM 3-SUBSTITUTED 1,2-CYCLOHEXANEDIONES BY USE OF DYE-SENSITIZED PHOTOOXYGENATION
A new synthesis of jasmine lactone and related δ-lactones is described which uses a novel dye-sensitized photooxygenation of 3-(2-alkenyl)- or 3-(2-alkynyl)-1,2-cyclohexanediones as a key step.
