polar additions or substitutions [71 induced us t o test the wider use of organotin deuterides for deuteration. Using powerful catalysts such as Raney nickel, palladium, platinum [El, or anhydrous ZnClz (91, we obtained both Cdeuterated and C,U-bisdeuterated alcohols smoothly from organotin deuteri
The first examples of intramolecular cyclopropanation reactions on a phosphonate template catalyzed by Rh2(OAc) 4 are described. These reactions proceed in excellent yield and give mixtures of the P-heterocycles cis-2a-d and trans-2a-d with moderate levels of diastereoselectivity. The diastereoselec
