benzylic, benzhydrylic, and propargylic alcohols in trifluoroethanol. A variety of different nitroalkanes bearing functional groups can be used in this SN1-typereaction to afford the desired products in quantitative yields. Different chiral nitro derivatives were submitted to this highly diastereoselective alkylation reaction with selected benzhydrols. A new, effective, and chiral pyrrolidine organocatalyst
