Abstract
Abstract Reductive radical cyclization of ketonitriles was catalyzed by Cp2TiCl2 in the presence of Me3SiCl, zinc powder and imidazole, giving the 2-amino-3-cyano-2-cyclopenten-1-ols in moderate to good yields with high trans selectivity (up to 94% trans). The influence of the catalyst, chlorosilane, co-reductant, solvent, and temperature on both the yield and diastereoselectivity of the cyclized products was investigated in detail.
