Title:
CHIRAL SALICYLALDEHYDE COMPOUND AND CHIRAL NAPHTHOLALDEHYDE COMPOUND FOR L / D OPTICAL TRANSFORMATION OF AMINO ACID, AND OPTICAL RESOLUTION OF AMINO ACID AND AMINOALCOHOL
Document Type and Number:
WIPO Patent Application WO/2010/120138
Kind Code:
A3
Abstract:
The present invention relates to a salicylaldehyde chiral compound (chemical formula 1) and a naphtholaldehyde chiral compound (chemical formula 2), wherein a –OH group and a carbonyl group are adjacent to each other on a benzene ring. Both compounds contain an asymmetric carbon and have relatively small molecular weight compared to that of known binaphthol derivatives. Optical transformation of amino acid and optical resolution of amino acid and aminoalcohol can be effectively carried out by the salicylaldehyde chiral compound (chemical formula 1) and naphtholaldehyde chiral compound (chemical formula 2) of the present invention.
