Title:
OPTICALLY PURE DIAMIDES AND THE PREPARATION AND USES THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/065292
Kind Code:
A1
Abstract:
A type of optically pure diamides, which have the general formula as follows.
The configuration is L or D, wherein Het represents 4-8 membered heterocycles
contaning nitrogen atom on the backbone; each of R1, R2,
R3 is hydrogen, hydrocarbonyl, substituted hydrocarbonyl, hydrocarbonyl
containing heteratom or hydrocarbonyl containing heteratom in substituted
group; R1 and R2, or R2 and R3 link together
to form 3-8 membered heterocycles, X is hydrogen or oxygen, Y is carbonyl, sulfonyl
or phosphoryl; R4 is hydrocarbonyl, substituted hydrocarbonyl,
hydrocarbonyl containing heteratom or ZR4(wherein Z is hydrogen
or oxygen). The compounds of the present invention can be used as catalysts in
selective catalytic hydrogen transfer reduction of imines. And the preparation
of the type of the compounds.
