Allylic phosphine oxides 6 undergo asymmetric dihydroxylation to yield 1,2 diols 9. The enantioselectivity of these reactions depends critically on the class and quantity of chiral ligand used. A model to explain the sense and degree of asymmetric induction is proposed.

Title tandem reaction was achieved by using alpha-(trimethylsilyl)alkylphosphine chalcogenides and the lithio derivative of 2-hydroxytetrahydropyran. The Horner-Emmons reaction of the tandem products was accomplished to give the corresponding 2-(beta-styryl)tetrahydropyran derivatives by in situ generation and trapping of alpha-lithio derivatives, followed by Warren's method of olefination.
