Reference of 57-48-7, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 57-48-7, Name is (3S,4R,5R)-1,3,4,5,6-Pentahydroxyhexan-2-one, SMILES is [H][C@@](O)(CO)[C@@]([H])(O)[C@]([H])(O)C(=O)CO, belongs to chiral-catalyst compound. In a article, author is Liu, Hui, introduce new discover of the category.
The first enantioselective dearomative [3+2] annulation of 5-amino-isoxazoles with quinone monoimines was realized using a chiral phosphoric acid as catalyst. Various novel (bridged) isoxazoline fused dihydrobenzofurans bearing two continuous quaternary stereocenters were achieved in moderate to good yields (up to 94%) with moderate to good enantioselectivities (up to 98% ee). The absolute configurations of two products were assigned by X-ray crystal structural analyses and a plausible reaction mechanism was proposed.
