New synthesis of jasmine lactone and related .delta.-lactones from 1,2-cyclohexanedione. Preparation and dye-sensitized photooxygenation of 3-(2-alkenyl)- and 3-(2-alkynyl)-1,2-cyclohexanediones
A newsynthesis 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.
