The fate of the aryl gold(I) carbenes generated by retro-Buchner reaction of ortho-substituted 7-aryl-1,3,5-cycloheptatrienes is dependent on the constitution of the ortho substituent. Indenes and fluorenes are obtained by intramolecular reaction of highly electrophilic gold(I) carbenes with alkenes and arenes. According to density functional theory calculations, the gold-catalyzed retro-Buchner process

An efficient rhodium/olefin–sulfoxide catalyzed asymmetric conjugateaddition of organoboronic acids to a variety of nitroalkenes has been developed, where 2-methoxy-1-naphthyl sulfinyl functionalized olefin ligands have shown to be highly effective and are applicable to a broad scope of aryl, alkyl, and heteroaryl nitroalkenes.
There is provided a selective serotonin reuptake inhibitor having affinity for serotonin 1A receptors which comprises a cyclic amine represented by the formula:
wherein G represents a formula (2):
a prodrug of said cyclic amine, or a pharmaceutically acceptable salt of said cyclic amine or prodrug, as an active ingredient.
