Saha, Satyajit published the artcileFunctionalized proline with double hydrogen bonding potential: highly enantioselective Michael addition of carbonyl compounds to ¦Â-nitrostyrenes in brine, Category: catalysis-chemistry, the publication is Tetrahedron Letters (2010), 51(40), 5281-5286, database is CAplus.
Simple synthetic manipulation of S-proline allows access to prolinamides as catalysts capable of double hydrogen bonding for enantioselective Michael addition reactions of carbonyl compounds to ¦Â-nitrostyrenes. It is shown that prolinamide catalyst I leads to addition products with a high diastereo- as well as enantioselectivity. The transition state structure involving the binding of electrophilic nitrostyrene via two H-bonds is believed to be further stabilized by ¦Ð,¦Ð stacking interactions mediated by the tosyl ring.
