Abstract: | 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. |
