Compounds derived from indole, notably useful in therapeutics, selected from:
i) the compounds of formula:
and
ii) the pharmaceutically acceptable salts of the compounds of formula (I);
in which R1, R2, R3, R4, R5, R6, R8, R9 and Cy have defined meanings, and the use of such compounds in pharmaceuticals for the treatment of neurodegenerative diseases, particularly Parkinson's disease.

intermediate tertiary carbocations. This approach has been implemented to achieve the first example of enantioselective reductive deoxygenation of tertiaryalcohols. This reduction occurs with high enantio- (up to 96% ee) and regioselectivity (up to >50:1 rr) by applying a novel Hantzsch ester analogue as a convenient hydride source. In-depth mechanistic studies support the involvement of a tertiary carbocation
photoactivation of the electrondonor–acceptor (EDA) complex. The reaction avoids the requirement for photocatalysts, bases, hydrogen donor reagents, any other additives, and harsh conditions, enabling the facile synthesis of various functionalized γ-hydroxy (E)-alkenylsulfonyl fluorides. These multifunctional sulfonyl fluorides can be further diversified, providing access to various privileged molecules
基于电子供体-受体 (EDA) 复合物的光活化,提出了使用 FSO 2 Cl 进行炔丙醇的自由基氢氟磺酰化。该反应不需要光催化剂、碱、供氢试剂、任何其他添加剂和苛刻的条件,从而能够轻松合成各种官能化的γ-羟基( E )-烯基磺酰氟。这些多功能磺酰氟可以进一步多样化,提供各种具有生物相关性的特殊分子。
