Sc(OTf)3a'Catalyzed Ca'C Bond-Forming Reaction of Cyclic Peroxy Ketals for the Synthesis of Highly Functionalized 1,2-Dioxene Endoperoxides

A new and general Sc(OTf)3-catalyzed C-C bond-forming reaction of 3-(2-methoxyethoxy)-endoperoxy ketals with silyl ketene acetals, silyl enol ethers, allyltrimethylsilane, and trimethylsilyl cyanide has been developed via the reactive peroxycarbenium ions, affording a wide range of complicated 3,3,6,6-tetrasubstituted 1,2-dioxenes bearing adjacent quaternary carbons and 3-acetyl/allyl/cyano functional groups in good yields at room temperature. Notably, the resultant 1,2-dioxenes are structurally stable, which can be facially transformed into another important 1,2-dioxane endoperoxide under conventional hydrogenation conditions without deconstructing the weak O-O bond.

α:γ RATIOS IN PHENYLTHIOMETHYLATION OF SILYL DIENOL ETHERS

We report α:γ ratios for the electrophilic attack of phenylthiomethyl chloride on all the possible 2- and 4-methylated 1-phenyl-1-trimethylsilyloxybutadienes (7a-7e); the methyl groups appear to reduce the proportion of attack taking place at the carbon atom carrying the methyl groups.
