Synthesis of α-methyl kainic acid by stereospecific lithiation-dearomatizing cyclization of a chiral benzamide
Clayden, Jonathan,Knowles, Faye E.,Menet, Christel J.
, p. 3397 - 3400 (2003)
Stereospecific lithiation of N-α-methylbenzyl benzamides gives configurationally stable tertiary benzyllithiums which undergo a stereospecific dearomatizing cyclization with >99% retention of stereochemistry. The products are partially saturated isoindolinones which carry a new fully-substituted stereogenic centre. A ten-step sequence converts one of these products to the α-methyl analogue of kainic acid.

(Matrix presented) Chloral or its hydrate undergoes the carbon-carbon bond-formation reaction with various optically active imines in the absence of any additive, followed by hydrolysis, to produce the corresponding β-trichloromethyl-β-hydroxy ketones in
NADH MODELS XXI. STEREOSELECTIVE REDUCTION OF CHIRAL IMINES WITH HANTZSCH ESTER
van Niel, Johannes C.G.,Pandit, Upendra K.
, p. 6005 - 6012 (2007/10/02)
Imines derived from p-substituted acetophenones and (+) R-1-phenylethylamine are reduced by 3,5-diethoxycarbonyl-2,6-dimethyl-1,4-dihydro-pyridine (Hantzsch ester), in acetonitrile, in the presence of magnesium perchlorate, to diastereomeric mixtures of t
