C–C Bond formation catalyzed by natural gelatin and collagen proteins

Autor: Dennis Kühbeck, Basab Bijayi Dhar, Eva-Maria Schön, Carlos Cativiela, Vicente Gotor-Fernández, David Díaz Díaz

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 9, Iss 1, Pp 1111-1118 (2013)

The activity of gelatin and collagen proteins towards C–C bond formation via Henry (nitroaldol) reaction between aldehydes and nitroalkanes is demonstrated for the first time. Among other variables, protein source, physical state and chemical modif
