- W2364832958 abstract "OBJECTIVE To synthesize a cheap ligand and determine it's catalytic activities in asymmetric dihydroxylation(AD)reaction and to get ethyl-(2R,3S)-dihydroxy-3-phenylpropionate with high yield and enantioselectivity.METHODS The new chiral ligand (QN)_2PYDZ was synthesized by cheap material 3,6-dichoropyridazine,which was applied to AD reaction of six olefins. RESULTS The ligand was obtained with lower cost by convenient process,which had satisfying catalytic activities in AD reaction.CONCLUSION The ligand (QN)_2PYDZ can be used to prepare ethyl-(2R,3S)-dihydroxy-3-phenylpropionate with high yield (90%) and enantioselectivity (99%),a precursor of C_ 13 side chain of taxol and the process is economical and adaptable." @default.
