Palladium-catalyzed decarboxylation of 5-methylene-1,3-oxazinan-2-ones and 5-methylene-1,3-dioxan-2-ones to generate aza-π-allylpalladium oxa-π-allylpalladium 1,4-dipoles for [4 + 2] cycloaddition reaction with 1,3,5-triazinanes was developed, affording a wide range hexahydropyrimidine 1,3-oxazinane derivatives in good excellent yields (up 99%). The acyclic sulfonamido-substituted allylic carbonates as 1,4-dipole precursors also apply the developed synthesized strategy, achieving synthesis hexahydropyrimidines. Moreover, situ-generated undergoing dimeric 4] were demonstrated by construction 1,5-diazocane derivatives.
