The invention concerns a spiro-amino compound of Formula (Vl) wherein m is 1 or 2 or 3, n is 1 or 2, R is selected from a 5- or 6-membered aromatic ring and a 5- or 6-membered heteroaromatic ring comprising 1 to 3 heteroatoms selected from S, O e N, such ring being substituted with one or two substituents selected from the group consisting of (C1-C3)alkyl, halogen, (C3-C5)cycloalkyloxy, (C1-C3)alkylcarbonyl, phenyl optionally substituted with one or more halogen atoms, a 5- or 6-membered heterocycle comprising at least one nitrogen atom; P is a substituent Q or COQ, wherein Q is selected from the group consisting of phenyl, pyridil, pyrimidil, quinolyl, isoquinolyl, quinoxalyl, benzofuranyl, imidazotriazolyl, being such Q optionally substituted with one or more substituents selected from the group consisting of (C1-C3)alkyl, halogen, trifluoromethyl, carbammido, methylcarbammido, carboxy, methylcarboxy or a pharmaceutically acceptable salt thereof.
catalytic reactions using transition metals is an important challenge in organic chemistry in which the intermediates are related to those produced in the classical cross-couplingreactions. As part of our research program devoted to the development of metal-catalyzed reactions using indium organometallics, a protocol for the C⁻H activation and C⁻C coupling of 2-arylpyridines with triorganoindium reagents

A novel Pd(OAc)2-catalyzed methylation reaction by dicumylperoxide via aryl C−H bond activation was discovered. Various 2-phenylpyridine and acetanilides can be used as reactants in these reactions. Peroxide was used as both the methylatingreagent and the hydrogenacceptor.
