ABSTRACT:
Supported phase catalysts in which the support phase, is non-aqueous and highly polar, such as a primary alcohol, and most preferably ethylene glycol, are. disclosed. An organometallic compound, preferably a metal complex of chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl is dissolved in the ethylene glycol. Such supported phase catalysts are useful for asymmetric synthesis of optically active compounds, such as the preparation of dehydronaproxen.
