or a pharmaceutically acceptable salt or derivative thereof. The compounds of formula I exhibit affinity for alpha2 adrenoceptors.
gold(I)‐catalyzed synthesis of indanones from trimethylsilylacetylenes and acylsilanes is presented. The reaction is initiated through a synergistic acylsilane activation–gold acetylide formation and involves consecutive alkyne σ‐gold(I) addition, π‐activation, and 1,2‐migration of a silyl group. Studies performed on the reaction mechanism allowed to establish the nature of the silyl migrating group and invoke the

Methods and compositions useful in the treatment or prevention of synucleinopathies, such as Parkinson's disease, diffuse Lewy body disease, and multiple system atrophy, or other neurodegenerative diseases (e.g., amyotrophic lateral sclerosis, Huntington's disease, and Alzheimer's disease) are provided. The treatment including administering to a subject an indatraline derivative that inhibits the aggregation of α-synuclein.
homologation of unstrained aryl ketones through a formal 1,1-insertion process of olefins, enabled by temporary directing group (TDG)-aided C–C activation. The reaction provides a distinct approach to access various substituted 1-indanones. Computational mechanistic studies reveal that the formal 1,1-insertion is realized by a selective C(sp2)–C(sp3) activation and turnover limiting 2,1-insertion into

Golden tendencies: The title reaction for synthesizing cyclopentenonederivatives utilizes a gold complex and 8‐methylquinoline oxide as the catalyst system (see scheme; IPr=1,3‐bis(diisopropylphenyl)imidazol‐2‐ylidene). Such products are not attainable using diazocarbonyl reagents, as the gold carbenoids tend to react with CH bonds.
