Stereoselective reductive radical cyclization of ketonitriles catalyzed by Cp2TiCl2 in the presence of chlorosilane and zinc
Zhou, Longhu,Hirao, Toshikazu
, p. 6927 - 6933 (2001)
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 selec
Conjugate addition of malononitrile on chalcone: Biocatalytic [Formula presented] bond formation
Punyapreddiwar, Nitesh D.,Zodape, Sangesh P.,Wankhade, Atul V.,Pratap, Umesh R.
, p. 124 - 126 (2016/08/23)
An efficient, cost effective and environmentally friendly protocol has been developed for the Michael addition of malononitrile on 1,3-diaryl-2-propen-1-ones (Chalcones) using very cheaper, easily available natural catalyst, baker's yeast. The whole cells of yeast excellently worked in nonaqueous medium, ethanol without decrease in catalytic activity.
Back to natural cinchona alkaloids: Highly enantioselective Michael addition of malononitrile to enones
Russo, Alessio,Perfetto, Alessandra,Lattanzi, Alessandra
supporting information; experimental part, p. 3067 - 3071 (2010/04/06)
An efficient and convenient highly enantioselective Michael addition of malononitrile to enones has been developed by using quinine as the organocatalyst. The adducts were isolated in excellent yield and high asymmetric induction (up to 95% ee). An easy r
