Otomo, Ryoichi,Osuga, Ryota,Kondo, Junko N.,Kamiya, Yuichi,Yokoi, Toshiyuki
, p. 20 - 24 (2019)
Ion-exchange of an Al-rich zeolite beta, synthesized by organic structure-directing agent-free method (Beta-OF), was studied for application as a base catalyst. While the as-synthesized Beta-OF in Na-form itself had base sites and showed moderate catalyti

A reinvestigation of a chiral phosphoric-acid-catalyzed four-component Hantzsch enantioselective synthesis of polyhydroquinolines reported in 2009 is presented. In our hands, when the reaction was performed with fidelity to the original report using a chiral enantiopure phosphoric acid catalyst, no enantioselectivity was observed. Unlike in the original report, enantioselectivity results are backed by baseline separation of the enantiomers by HPLC analyses on chiral stationary phase with UV and chiroptical detection.
Highly active hybrid mesoporous silica-supported base organocatalysts for C–C bond formation
Erigoni,Hernández-Soto,Rey,Segarra,Díaz
, p. 227 - 236 (2019/10/28)
New base hybrid catalysts, based on silyl-derivatives of molecules carrying amino, diamino, pyrrolidine, pyrazolium and imidazolium functionalities have been successfully achieved through post synthetic grafting onto M41S-type support. Different character
