A palladium-catalyzed highly regioselective C-H allylation/annulation reaction of N-sulfonyl amides with secondary or tertiary allylic alcohols provides 3,4-dihydroisoquinolones bearing a synthetically valuable vinyl substituent. Commercially available allylic alcohol substrates, water as only by-product, and O2 as terminal oxidant make the use of this process advantageous.
