Asymmetric Syntheses of Amino Acids by Addition of Cyanide to the Schiff Bases in the Presence of Cyanide-Modified Hemin-Copolymer
Saito, Kiyoshi,Harada, Kaoru
, p. 4535 - 4538 (2007/10/02)
Sterically controlled addition reactions of CN group to the Schiff bases by using CN-modified hemin-copolymer were carried out, and the optical yields (80-95 e.e.) of the resulting amino acids were much higher than that obtained without hemin-copolymer.
Diastereoface-Differentiating Synthesis of Substituted β-Lactams from Chiral Imines and/or Chiral α-Chloro Iminium Chlorides

Reaction of imines carrying a chiral substituent at a nitrogen atom with symmetric or prochiral α-chloro iminium chlorides leads in a diastereoface-differentiating reaction to a mixture of diatereoisomeric or epimeric β-lactams.Attempts were made to determine the absolute configuration of obtained chiral β-lactams.Reaction of prochiral imines with chiral α-chloro iminium chlorides also provides mixtures of diastereomeric β-lactams or their enantiomers with a clear selectivity.
ASYMMETRIC ADDITION OF TRIS(TRIMETHYLSILYL) PHOSPHITE TO CHIRAL ALDIMINES
ZON, Jerzy
, p. 643 - 646 (2007/10/02)
Addition of tris(trimethylsilyl) phosphite (2) to (+)-(R)-1-phenylethylaldimines (1) and methanolysis of addition products affords(+)-N-(1-phenyethyl)-1-aminoalkanophosphonic acids (3).Chemical yields and diastereomeric composition of 3 vary from 10 to 90
