Successive Carbon–Carbon Bond Formation by Sequential Generation of Radical and Anionic Species with Manganese and Catalytic Amounts of PbCl<sub>2</sub>and Me<sub>3</sub>SiCl
moderate reducing system derived from manganesemetal and a catalyticamount of PbCl2 and Me3SiCl. Although the role of PbCl2 is unclear, addition of a catalyticamount of the salt is essential for reducing the iodoalkane. The reaction proceeds with primary, secondary, and tertiary iodoalkanes. Both acrylonitrile and acrylic esters can be employed as activated olefins, while the reaction with an alkyl

[EN] The present invention relates to cyclopropyl derivatives of formula (I) and salt thereof. These compounds are NK3 receptor antagonists and may therefore be useful for treatment of diseases where the NK3 receptor is implicated, e.g. psychotic disorders. [FR] Cette invention se rapporte à des dérivés de cyclopropyle représentés par la formule (I) et à des sels de ces dérivés. Ces composés constituent des antagonistes du récepteur de NK3 et ils peuvent par conséquent être utiles pour le traitement des maladies dans lesquelles est impliqué le récepteur de NK3, par exemple les troubles psychotiques.

Rh‐catalyzed carbonylative C−C bond activation of cyclopropylamides generates configurationally stable rhodacyclopentanones that engage tethered alkenes in (3+1+2) cycloadditions. These studies provide the first examples of multicomponent cycloadditions that proceed through C−C bond activation of “simple” electron poor cyclopropanes.
