  Transition Metal-Catalyzed Hydro-, Sila-, and Stannastannation of Cyclopropenes:  Stereo- and Regioselective Approach toward Multisubstituted Cyclopropyl Synthons

  摘要：

  The first highly efficient, stereo- and regioselective palladium-catalyzed hydro-, sila-, and stannastannation of cyclopropenes to give multisubstituted cyclopropylstannanes have been developed. It was shown that the addition across the double bond of cyclopropene is generally controlled by steric factors and proceeds from the least hindered face. The directing effect of alkoxymethyl substituents in the hydrostannation reaction of 3,3-disubstituted cyclopropenes was demonstrated. This methodology represents a powerful and atom-economic approach toward a wide variety of highly substituted cyclopropylstannanes, important building blocks unavailable by other methods.

  CF3-cyclopropanes with aliphatic, aromatic, and even heteroaromatic substituents were prepared on a multigram scale by deoxyfluorination of cyclopropane carboxylic acids or their salts with sulfur tetrafluoride. For labile α-pyridine acetic acids, only the use of their potassium salts allowed to obtain the needed products. Derivatization of CF3-cyclopropanes into building blocks ready for direct use

• Catalytic Enantioselective Hydrostannation of Cyclopropenes
  作者：Marina Rubina、Michael Rubin、Vladimir Gevorgyan

  DOI：10.1021/ja0496928

  日期：2004.3.1

  The first examples of catalytic enantioselective hydrostannation of the C=C double bond of cyclopropenes has been demonstrated. This method allows for the efficient synthesis of 2,2-disubstituted cyclopropylstannanes with high degrees of diastereo- and enantioselectivity. The facial selectivity of this reaction is entirely controlled by steric factors. A variety of functional groups at C-3 of the cyclopropenes were tolerated.
