Rodríguez Ferrer, Patricia Naharro, Daniel Maestro Fernández, Alicia Andrés García, José María Pedrosa Sáez, Rafael 2019 Producción Científica Four novel chiral bifunctional thiosquaramides have been prepared from cyclopentyl dithiosquarates and diamines derived from natural l‐Valine and l‐tert‐Leucine. The novel thiosquaramides have been tested as organocatalyst in the nitro‐Michael addition of 3‐substituted oxindoles to different β‐aryl‐substituted nitroalkenes. The reaction occurred easily in high yields and excellent stereoselectivities, showing that the novel organocatalysts are much more effective than their thioureas and squaramides homologs. application/pdf http://uvadoc.uva.es/handle/10324/38452 eng Willey Química orgánica Chiral Bifunctional Thiosquaramides as Organocatalysts in the Synthesis of Enantioenriched 3,3-Disubstituted Oxindoles info:eu-repo/semantics/article TEXT UVaDOC.
