On July 24, 2014, Basarab, Gregory Steven; Gowravaram, Madhusudhan Reddy; Hauck, Sheila Irene; Zhou, Fei published a patent.Recommanded Product: (R)-5-(Hydroxymethyl)oxazolidin-2-one The title of the patent was Preparation of spiro[oxazino[4,3-a]isoxazolo[4,5-g]quinoline-pyrimidine]trione compounds and methods for treating bacterial infections. And the patent contained the following:
Compounds of formula I, pharmaceutically acceptable salts thereof, and uses of the compounds of formula I for treating bacterial infections are disclosed. Compounds of formula I wherein X is F and Cl; R1 is H, (un)substituted Ph, CN, tetrahydropyranyl, etc.; R2 is H, CN, pyridinyl and (un)substituted C1-3 alkyl; R3 is H and C1-3 alkyl; and pharmaceutically acceptable salts thereof, are claimed. Example compound II was prepared by spirocyclization of (2R)-1-[[5-(1,3-Dioxolan-2-yl)-6,7-difluoro-1,2-benzoxazol-3-yl]amino]propan-2-ol with barbituric acid. The invention compounds were evaluated for their DNA gyrase inhibitory activity (data given). The experimental process involved the reaction of (R)-5-(Hydroxymethyl)oxazolidin-2-one(cas: 97859-49-9).Recommanded Product: (R)-5-(Hydroxymethyl)oxazolidin-2-one
