Enantioselective Redox-Divergent Chiral Phosphoric Acid Catalyzed Quinone Diels–Alder Reactions

An efficient enantioselective construction of tetrahydronaphthalene-1,4-diones as well as dihydronaphthalene-1,4-diols by a chiral phosphoric acid catalyzed quinone Diels–Alder reaction with dienecarbamates is reported. The nature of the protecting group on the diene is key to the success of achieving high enantioselectivity. The divergent “redox” selectivity is controlled by using an adequate amount of quinones. Reversible redox switching without erosion of enantioselectivity was possible from individual redox isomers.

A convenient new route to enantiopure 3-hydroxy-5-oxo esters and 5,6-dihydropyran-2-ones: intricacies of the trithioorthoester protecting group

3-Hydroxy-5-oxo esters are useful precursors to biologically active compounds. An expedient three-step synthesis of 3-hydroxy-5-oxo esters based on dithiane anion chemistry is presented along with the transformation of the 3-hydroxy-5-oxo esters into 5,6-dihydropyran-2-ones.

A NEW METHOD FOR SYNTHESIS OF α,β-UNSATURATED δ-LACTONES VIA MICHAEL ADDITION USING METHYL (PHENYLSULFINYL)ACETATE

Various α,β-unsaturated δ-lactones were synthesized via Michael addition of methyl (phenylsulfinyl)acetate to alkyl vinyl ketones in the presence of tributylphosphine.For example, racemic massoia lactone was obtained in 49percent overall yield.
