Title:
Polystyrene support pyridine screw oxazoline derivative-calcium catalyst
Document Type and Number:
Japanese Patent JP6011769
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To immobilize a complex to which a chiral calcium pyridine bisoxazoline derivative is coordinated.SOLUTION: As shown in chemical reaction formula (11), CaXis reacted with a pyridine bisoxazoline derivative having a polystyrene bridged structure prepared by mutually mixing at an arbitrary ratio and at random (4S,4'S,5S,5'S)-2,2' (4-vinylpyridine-2,6-diyl) bis(4,5-diphenyl-4,5-dihydroxazole), styrene and divinylbenzene (including ethyl vinyl benzene).
