A compound of formula (I):
or, where appropriate, a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable solvate thereof
wherein
A represents >C=X, wherein
X represents oxygen or sulphur, or A represents a bond;
Y represents N or N⁺-O⁻ or a moiety CR₈,
and the other substituents are defined as in claim 1;
a process for the preparation of such a compound, a pharmaceutical composition comprising such a compound and the use of such a compound and composition in medicine.
The palladium-catalyzed skeletal rearrangement of 3-arylcyclobutanones into 1-indanones is reported. A Pd(0)/IMes catalyst allows for the cleavage of C(carbonyl)–C(sp3) and C(sp2)–H bonds to result in the skeletal rearrangement, and neither an extra reactive functional group nor a directing group is required to promote the reaction. Deuterium-labeling experiments indicate that the C–C bond is initially
Novel indane and quinoline derivatives, useful, for example, as antiischemic agents, having the formula
where A, X, R₁-R₇ are as defined herein, are disclosed.
新颖的茚满和喹啉衍生物,可用作抗缺血剂等,其式为
其中 A、X、R₁-R₇ 如本文所定义。
