A copper(I)/DDQ-mediated double-dehydrogenative Diels-Alder (DDDA) reaction of simple butenes with 1,4-diketones and indolones has been established for the first time. This strategy is based on a tandem double-dehydrogenation/Diels-Alder reaction from nonprefunctionalized starting materials, in which both a diene and dienophile were in situ generated via activation of fourfold inert C(sp3)-H bonds in one catalytic system.

Thiazolium salt-catalysed addition of aliphatic, aromatic, and heterocyclic aldehydes to phenyl vinyl sulfone yields in a three-step addition-elimination mechanism 1,4-diketones (1 - 3) and 1,4-disulfone (23).The analogous reaction with divinyl sulfone leads in good yields to the corresponding 1,4-diketones (1 - 22).
