Gold-catalyzed formal hetero-[4π+2π] cycloadditions of tert-butyl propiolates with carbonyl compounds proceeded efficiently to yield 4H-1,3-dioxine derivatives over a wide scope of substrates. With acetone as a promoter, gold-catalyzed cycloadditions of these propiolate derivatives with enol ethers led to the formation of atypical [4+2]-cycloadducts with skeletal rearrangement.

5-Aryl-2,3-dihydrofuran-2,3-diones react with aldehydes, ketones, and α-ketoesters to form 2,2,5,6-tetrasubstituted 1,3-dioxen-4-ones.The reaction of 5-aryl-2,3-dihydrofuran-2,3-diones with α-diketones occurs either at one carbonyl group of the α-ketone to form 2,6-disubstituted 1,3-dioxen-4-ones or at both carbonyl groups to form 2,2',6,6'-tetrasubstituted 4,4'-dioxo-2,2'-bi(1,3-dioxenyls).
