NOVEL AND EFFICIENT ONE-POT SYNTHESIS OF PHOSPHORUS HETEROCYCLES CONTAINING THE BICYCLOHEPTENE MOIETY

In a convenient one-pot sequence, treatment of camphorquinone with sodium in dry tetrahydrofuran followed by addition of phosphorodichloridate and phosphorothiodichloridate yields 2-oxo-1,3,2-dioxaphospholes and 2-thioxo-1,3,2-dioxaphospholes, respectively.Similar treatment of 3-phenyliminobornan-2-one with sodium in dry THF followed by addition of phosphorodichloridate and phsphorothiodichloridate yields 2-oxo-1,3,2-oxazaphospholes and 2-thioxo-1,3,2-oxazaphospholes.Key words: Camphorquinone, 3-phenyliminobornan-2-one, phosphorodichloridate, phosphorothiodichloridate, dioxaphospholes, oxazaphospholes.

Asymmetric Carboalkoxyalkylidenation with a Chiral Horner-Wadsworth-Emmons Reagent

The asymmetric carboalkoxyalkylidenation of 4-substituted cyclohexanones was effected by the use of chirally modified Horner-Wadsworth-Emmons (HWE) reagents in good yields (78-82percent) as well as high levels of enantioselectivity (78-86percent ee).
