描述了一种室温镍催化的还原方法,用于未活化的伯,仲和叔烷基溴的均相偶联。催化体系可以容易地由空气稳定且廉价的材料产生,并显示出宽泛的官能团耐受性,因此可以轻松获得有用的二聚三萜和木脂素样分子。而且,叔溴化物6的二聚作用有效地建立了位阻式邻位季碳(C3a和C3a'),这是有趣的双吡咯并[2,3- b ]二氢吲哚生物碱的关键连接,从而使我们能够完成总外消旋体的合成。烟嘌呤(9)和叶硫蒽(10))。另外,该二聚方法可扩展为双过氢呋喃[2,3- b ]呋喃(5a)和二聚螺酮5b的高度立体选择性合成,这表明可能涉及自由基。

The present disclosure relates to bifunctional compounds, which find utility as modulators of tau protein. In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a VHL or cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds tau protein, such that tau protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of tau. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of tau protein. Diseases or disorders that result from aggregation or accumulation of tau protein are treated or prevented with compounds and compositions of the present disclosure.

Problem to be Solved
It is intended to provide an industrially preferable fluoroalkylating agent and use thereof.
Solution
The present invention provides a fluoroalkylating agent represented by the general formula (1) wherein R
1
is a C1 to C8 fluoroalkyl group; R
2
and R
3
are each independently a C1 to C12 alkyl group or the like; Y
1
to Y
4
are each independently a hydrogen atom, a halogen atom, or the like; and X
−
is a monovalent anion.
A compound of the general formula (3): R
4
—S—R
1
having an introduced C1 to C8 fluoroalkyl group is easily obtained by reacting a compound of the general formula (2): R
4
—S—Z wherein R
4
is a hydrocarbon group or the like; and Z is a leaving group, with the compound of the general formula (1).
