合成了一系列的4-烷基或4-苯基取代的2,3-二氢-6 H -1,3-噻嗪-5-羧酸酯,并在甲苯中光解。4-甲基化合物重排为噻唑烷,噻唑烷在溶液中以亚氨基互变异构体形式共存。4-乙基衍生物基本上给出了无环硫代酰胺基-二烯的单一异构体,而4-苄基衍生物给出了所有四种可能的硫代酰胺基-二烯的混合物。4-苯基衍生物产生骨架重排的2,5-二氢-6 H -1,3-噻嗪,其缓慢重排为相应的2,3-二氢-6 H -1,3-噻嗪。

The present invention relates to compounds useful as inhibitors of one or more histone demethylses, such as KDM5. The invention also provides pharmaceutically acceptable compositions comprising compounds of the present invention and methods of using said compositions in the treatment of various disorders.
Reactions of 5-aminoisoxazoles with α,β-unsaturated ketones in t-butanol on heating afforded 4,7-dihydroisoxazolo [5,4-b]pyridines. However, when the reactions were carried out at 20° using ethylene glycol as the solvent, the kinetically controlled amino adducts were obtained in excellent yields. The amino adducts were converted into the thermodynamically controlled 4,7-dihydroisoxazolo[5,4-b]pyridines
Provided are compounds useful as inhibitors of one or more histone demethylases, such as KDM5. The invention also provides pharmaceutically acceptable compositions comprising compounds of the present invention and methods of using the present composition in the treatment of various disorders.
