  Abstract: Green Chem. , 2013, Accepted Manuscript
  DOI : 10.1039/C3GC00062A, Paper Norbert Hoffmann, Sinisa Marinkovic, Abdoulaye Gassama, Cedric Ernenwein, Ali Youssef, Emmanuel Riguet, Boris Estrine, Mickael Agach Furfural obtained from pentose containing biomass such as hemicelluloses is subjected to photooxygenation. The resulting hydroxyfuranone obtained in high yields undergoes acetalization with fatty alcohols. Using NaHSO3, surfactants are obtained...

Carbon dioxide as a reversible amine-protecting agent in selective Michael additions and acylations
- Authors: Annelies Peeters; Rob Ameloot, Dirk E. De Vos
  Abstract: Green Chem. , 2013, Accepted Manuscript
  DOI : 10.1039/C3GC40568K, Paper Annelies Peeters, Rob Ameloot, Dirk E. De Vos Carbon dioxide can be used as a temporary protecting group for amines. A carbamic acid is formed reversibly when CO 2 is bubbled through a solution of a sufficiently basic primary... The content of this RSS Feed (c) The Royal Society of Chemistry
