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.
