Synthesis and stereochemical assignments of diastereomeric Ni(II) complexes of glycine Schiff base with (R)-2-(N-{2-[N-alkyl-N-(1-phenylethyl)-amino]acetyl}amino) benzophenone; a case of configurationally stable stereogenic nitrogen
(Beilstein Institut, 2014-02-19)
A family of chiral ligands derived from alpha-phenylethylamine and 2-aminobenzophenone were prepared by alkylation of the nitrogen atom. Upon reaction with glycine and a Ni(II) salt, these ligands were transformed into ...
Ionic Liquids and Cellulose: Dissolution, Chemical Modification and Preparation of New Cellulosic Materials
(MDPI, 2014-07)
Due to its abundance and a wide range of beneficial physical and chemical properties, cellulose has become very popular in order to produce materials for various applications. This review summarizes the recent advances in ...
Enantioselective Construction of Tetrasubstituted Stereogenic Carbons through Brønsted Base Catalyzed Michael Reactions: α´-Hydroxy Enones as Key Enoate Equivalent
(ACS, 2014-11-25)
Catalytic and asymmetric Michael reactions constitute very powerful tools for the construction of new C–C bonds in synthesis, but most of the reports claiming high selectivity are limited to some specific combinations of ...
