Enantioselective synthesis of γ-tetrasubstituted nitrosulfonyl carboxylates and amides via L-tert-leucine-derived-squaramide catalyzed conjugate addition of nitrosulfones to acrylates and acrylamides

Bera, Kalisankar,Namboothiri, Irishi N.N.

supporting information, p. 6425 - 6431 (2014/08/18)

Michael addition of α-nitrosulfones to aryl- and alkyl acrylates and acrylamides proceeds in the presence of 5-10 mol% of an amino acid derived new organocatalyst to provide γ-tetrasubstituted γ-nitro-γ- sulfonyl carboxylates and amides in excellent yield
