Journal ArticleDOI
Basic character of rare earth metal alkoxides. Utilization in catalytic C-C bond-forming reactions and catalytic asymmetric nitroaldol reactions
TL;DR: In this article, the authors reported several carbon-carbon bond-forming reactions catalyzed by rare earth metal alkoxides and their application to a catalytic asymmetric nitroaldol reaction.
Journal ArticleDOI
Catalytic Asymmetric Synthesis of .alpha.-Amino Phosphonates Using Lanthanoid-Potassium-BINOL Complexes
TL;DR: The authors report here the first example of a catalytic asymmetric hydrophosphonylation to imines using lanthanoids-potassium-BINOL heterobimetallic complexes (LnPB, Ln = lanthanoid metal), which gives optically active {alpha}-amino phosphonates in modest to high enantiometric excess.
Journal ArticleDOI
Effects of rare earth metals on the catalytic asymmetric nitroaldol reaction
TL;DR: In this paper, the optical purities of nitroaldols obtained using these rare earth complexes as an asymmetric catalyst have been highly dependent on the size of rare earth metals, and the application to a catalytic asymmetric synthesis of (S )-metoprolol, a β 1 -selective β-blocker has been also achieved.
Journal ArticleDOI
First catalytic asymmetric hydrophosphonylation of cyclic imines: Highly efficient enantioselective approach to a 4-thiazolidinylphosphonate via chiral titanium and lanthanoid catalysts
TL;DR: A highly efficient enantioselective de novo approach to the pharmaceutically interesting 4-thiazolidinylphosphonate 2 using either titanium or lanthanoid chiral catalysts, which gives excellent enantiomeric purities and high chemical yields.
Journal ArticleDOI
Catalytic aldol reaction with Sm(HMDS)3 and its application for the introduction of a carbon-carbon triple bond at C-13 in prostaglandin synthesis
TL;DR: In this article, the authors studied catalytic effects of a Sm-(HDMS)-sub 3 complex in the regioselective formation of a triple bond in prostaglandin precursors.
