Wang, Li,Shen, Chun,Xu, Ming-Hua
experimental part, p. 61 - 65 (2011/12/15)
A facile and efficient method for the stereoselective synthesis of β-amino acid esters via SmI2-promoted imino-Reformatsky reaction is described. Asymmetric addition of tert-butyl bromoacetate to N-tert-butanesulfinyl aldimines afforded β-amino

A general simple procedure having the potential for large scale preparations of racemic β3-amino acids has been developed. The procedure involves base-catalyzed Michael-type addition of sodium diethyl malonate to N-Boc-α-amidoalkyl-p-tolyl sulfones in tetrahydrofuran. Hydrolysis of the adducts by refluxing with 6 M aqueous hydrochloric acid affords β3-amino acid hydrochlorides in high yield and excellent purity.
Self-Reproduction of Chirality. Asymmetric Synthesis of β-Aryl-β-amino Acids from Enantiomerically Pure Dihydropyrimidinones
Konopelski, Joseph P.,Chu, Kent S.,Negrete, George R.
, p. 1355 - 1357 (2007/10/02)
Enantiomerically pure dihydropyrimidinone 1 reacts with aryl iodides in the presence of catalytic amounts of Pd(OAc)2 and added phosphine to afford dihydropyrimidinone 4, in which a formal conjugate addition of the aryl group to the α,β-unsaturated system
