Scalable and economical methods for the production of optically pure amino acids, both natural and unnatural, are essential for their use as synthetic building blocks. Currently, enzymatic dynamic kinetic resolution (DKR) underpins some of the most e

Highly Diastereoselective Reduction of New Chiral α-Ketoamides
Autor: Yong Hae Kim, Il Suk Byun
Publikováno v: Synthetic Communications. 25:1963-1969
Both pyruvamide and benzoylformamide having (S)-2-methoxy-methylindoline as a chiral auxiliary were reduced with various reducing agents in high stereoselectivities (up to dr = 99 : 1).

Stereocontrolled enantioselective addition of diethylzinc to aldehydes using new chiral aminoalcohols
Autor: Doo Han Park, Yong Hae Kim, Il Suk Byun
Publikováno v: Heteroatom Chemistry. 3:51-54
The new chiral β-aminoalcohols of indolinylmethanols (1) and their reduced derivatives (2) were synthesized from (S)-indoline-2-carboxylic acid. Both (R) and (S) enantiomers of the optically active secondary alcohols have been successfully obtained

Highly diastereoselective addition of organometallics to novel chiral α-ketoamides of (S)-2-methoxymethylindoline
Autor: Yong Hae Kim, Il Suk Byun, Jun Young Choi
Publikováno v: Tetrahedron: Asymmetry. 6:1025-1026
The stereocontrolled nucleophilic addition of organometallics to novel chiral α-ketoamides which were synthesized from (S)-2-methoxymethylindoline as a chiral auxiliary was carried out to obtain α-hydroxyamides with extremely high diastereoselectiv
