Syntheses and radical polymerizations of methacrylamides derived from optically active amino alcohols were carried out. The monomers were prepared by condensation of optically active amino alcohols and methacrylic acid using l-ethyl-3-(3-dimethylamino-propy1)carbodiimide hydrochloride (EDC -HCl). Ra

Polycondensations of dicarboxylic acids with diols having amide moieties derived from optically active amino alcohols were carried out. Polymers with M V n s 8,700- 17,400 were obtained by the polycondensations using 1.2 eq. of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDCrHCl) i
The asymmetric reduction of ketoxime ethers to yield enantiomerically enriched chiral hydroxylamines with reagents prepared from borane and norephedrine has been investigated. Very high enantioselectivity (ca. 99% ee) was obtained in the reduction of ketoxime O-(o-nitrobenzyl) ether to O-(o-nitroben
Asymmetric Reduction of Ketoxime Ethers to Optically Active O-Substituted Hydroxylamines with Reagents Prepared from Borane and Chiral Amino Alcohols. -The reduction in the presence of norephedrine is an efficient method to prepare chiral O-substituted hydroxylamines. However, O-Tbs and O-tBu subst
