is the first report on the asymmetrictransferhydrogenation (ATH) of dibenzo[b,f][1,4]oxazepine compounds in the presence of an (R,R)-Ru-Ts-DPEN complex. The developed catalytic asymmetric protocol provides biologically active 11-substituted-10,11-dihydrodibenzo[b,f][1,4]oxazepines with excellent conversion (up to >99%) and high enantioselectivity (up to 93% ee) in water as an environmentally benign
The invention relates to the inhibition of histone deacetylase. The invention provides compounds and methods for inhibiting histone deacetylase enzymatic activity. The invention also provides compositions and methods for treating cell proliferative diseases and conditions.

Highly efficient asymmetrichydrogenation of dibenzo[b,f][1,4]oxazepine, dibenzo[b,f][1,4]thiazepine and dibenzo[b,e]azepine derivatives with chiral cationic ruthenium diamine catalysts has been developed, giving diverse chiral seven-membered N-heterocycles with excellent results (up to 99% yield and 99% ee). Moreover, it was found that the catalyst counteranion regulated the enantioselectivity obviously
二苯并[ b , f ][1,4]恶氮、二苯并[ b , f ] [1,4]硫氮和二苯并[ b , e ]氮杂衍生物与手性阳离子二胺钌催化剂的高效不对称氢化反应已被开发出来,得到多样的手性七元 N-杂环化合物,具有优异的结果(高达 99% 的产率和 99% 的 ee)。此外,发现催化剂抗衡阴离子在二苯并[ b,f ][1,4]噻氮和二苯并[ b,e ]衍生物的加氢反应中明显调节对映体选择性。

The present invention provides targeted treatment to subjects suffering from Frontotemporal lobar degeneration through use of FTLD targeted agents, as described in the present invention. In particular, the FTLD targeted agents provided herein demonstrate high brain penetration, which decreases risk issues associated with peripheral administration. Furthermore, the FTLD targeted agents of the present invention, when administered to a subject selected for treatment based on the results of a FTLD diagnostic assay, offer targeted treatment of FTLD.
