The present invention may provide an asymmetric hydrogenation catalyst capable of resolving enantiomers with excellent enantioselectivity from a carbon-carbon double bond-containing compound. The catalyst according to one embodiment of the present invention includes: an iridium cation; and a ligand bonded to the iridium cation.

Catalyst for asymmetric hydrogenation of compound containing carbon double bond

The present invention relates to a method for synthesizing a 3-phenyl-2,8-dihydropyrano[2,3-f]chromene derivative, which may be usefully used for synthesizing a pyranochromenyl phenol derivative, and when the derivative is used, the 3-phenyl-2,3,4,8,9,10-hexahydropyrano[2,3-f]chromene derivative may be effectively prepared.

Method for synthesizing 3-phenyl-2,8-dihydropyrano [2,3-f] chromene derivative

The present invention relates to pyranochromenylphenol derivatives having different efficacies depending on the direction of optical activity and a pharmaceutical composition including the same, and in the pyranochromenylphenol derivatives, an R-enantiomer has excellent anti-diabetic efficacy by suppressing a rise in blood sugar and an S-enantiomer has excellent anti-obesity efficacy by suppressing an increase in body weight.
