The singlet oxygen reactions of 4-methyl-2,4-hexadienoates E,E- and E,Z-4proceed in a highly mode selective and regioselective domino process. The initial product is the allylic hydroperoxide5directed by a vinylogous gem effect. The subsequent1O2[4 + 2] cycloaddition delivers a 3:2 diastereoisomeric mixture of 1,2-dioxanes8in a one-pot process. The identical protocol delivers from the more reactive α-methylated substrates E,E-10and E,Z-10with excellent primary regioselectivity the 1,2-dioxane13.
