Significance
Having recently introduced the squaramide motif in hydrogen-bonding catalysis (J. Am. Chem. Soc. 2008, 130, 14416), Rawal and colleagues now demonstrate its high efficiency in the Michael addition of diphenyl phosphite to nitroalkenes. Excellent enantiomeric induction and yields were observed for a range of nitroalkene substrates. Aliphatic and aromatic nitroalkenes were found to be equally suitable substrates.
