THE ASYMMETRIC MICHAEL PROCESS INVOLVING CHIRAL IMINES: THE DIASTEREOFACIAL DIFFERENTIATION ASPECT
d'Angelo, Jean,Revial, Gilbert,Guingant, Andre,Riche, Claude,Chiaroni, Angele
, p. 2645 - 2648 (1989)
A mechanism for the diastereofacial differentiation in the title reaction is proposed on the basis of the variation of the chiral auxiliary amines and of the examination of the crystal structure of enamino-ester 15.
Intramolecular reductive ketone-alkynoate coupling reaction promoted by (η2-propene)titanium
Schaefer, Christian,Miesch, Michel,Miesch, Laurence
supporting information; scheme or table, p. 3253 - 3257 (2012/06/01)
Intramolecular reductive coupling of cycloalkanones tethered to alkynoates in the presence of (η2-propene)titanium was successfully performed to provide hydroxy-esters in a diastereoselective manner. Subsequent lactonization afforded angularly
Asymmetric strecker synthesis of the four α-quaternary 1-amino-2-methylcyclohexanecarboxylic acids
Volk, Franz-Josef,Frahm, August Wilhelm
, p. 1893 - 1903 (2007/10/03)
The synthesis of the four 1-amino-2-methylcyclohexanecarboxylic acids 13, 14, 15, and 16 from diastereomeric mixtures of the α-amino nitriles 1-4 by successive application of conc. H2SO4, Pd/C H2, and conc. HCl is describe
