Enantioselective Addition of Diethylzinc to Benzaldehyde Catalyzed by an Organometallic Ti(IV) Compound and a Xylose Derivative
(SOC BRASILEIRA QUIMICA, 2009)
A derivative of D-xylose, 1,2-O-isopropylidene-alpha-D-xylofuranose (1), with Ti((OPr)-Pr-i)(4) was used as a chiral catalyst in the asymmetric alkylation of benzaldehyde with diethylzinc (Et2Zn) for the high-yield production ...
Enantioselective addition of diethyl zinc to benzaldehyde catalyzed by Ti(IV) and glucose derivatives
(Sociedad Chilena de Quimica, 2010)
D-Glucose derivatives 1,2:5,6-di-O-isopropyline-a-D-glucofuranose (1) and 1,2-O-isopropyline-a-D-glucofuranose (2) with Ti(IV) are chiral catalysts in the addition of diethylzinc to benzaldehyde. The Ti(IV)-carbohydrate ...

ENANTIOSELECTIVE ADDITION OF DIETHYLZINC TO BENZALDEHYDE CATALYZED BY AN ORGANOMETALLIC TI(IV) COMPOUND AND A XYLOSE DERIVATIVE
(SOCIEDADE BRASILEIRA DE QUIMICA, 2009)
Synthesis and application of chiral beta-amino disulfides as ligands for the enantioselective addition of diethylzinc to aldehydes
A new class of chiral beta-amino disulfides was synthesized from readily available and inexpensive starting materials by a straightforward method and their abilities as ligands were examined in the enantioselective addition ...
Development of polymer-supported chiral aminoalcohols derived from biomass and their application to asymmetric alkylation
(Pergamon-Elsevier Science Ltd, 2016-05)
A synthetic strategy has been developed for the preparation of immobilized 1,2-aminoalcohols starting from easily available and renewable chiral building blocks. They were tested as chiral ligands for the asymmetric ...
