The novel tris(triphenylphosphine)rhodiumchloride/boron trifuoride etherate [RhCl(PPh3)3/BF3⋅OEt2] co-promoted the CC cross-coupling of tertiary alcohols at the β-position with aldehydes. This reaction provides an efficient synthesis of either structurally diverse 1,3-diols or polysubstituted tetrahydropyrans by controlling the substrate structures, and it could be developed to a practical synthetic
