-
Paragraph 631; 632, (2015/05/06)
The present invention relates to novel oxodihydropyridinecarbohydrazide derivatives with excellent antifungal activities, an antifungal composition containing the same, and its use for the prevention and treatment of fungal infectious diseases. The oxodihydropyridinecarbohydrazide derivatives of the present invention have excellent antifungal and fungicidal activities, and thus will be useful for the prevention and treatment of various fungal infections by Candida spp., Aspergillus spp., Cryptococcus neoformans and Trichophyton spp., etc. Additionally, the oxodihydropyridinecarbohydrazide derivatives of the present invention, unlike other fungicidal preparations, can be orally administered.

A transition-metal-free method for the synthesis of C6 phenanthridine derivatives by arylative cyclization of 2-isocyanobiphenyls with arylamines in one pot was developed. Mechanistic studies suggest that electrophilic aromatic substitution (SEAr) of a nitrilium intermediate and homolytic aromatic substitution (HAS) of an imidoyl radical intermediate are two competitive reaction pathways involved in the annulation step.
Cyclizing radical carboiodination, carbotelluration, and carboaminoxylation of aryl amines

supporting information, p. 8180 - 8183 (2014/08/18)
Radical carboiodination of various aryl amines is reported. Aryl diazonium salts, generated in situ from the corresponding aryl amines, are reacted with Bu4NI to provide the corresponding aryl radicals which undergo 5-exo or 6-exo cyclization. Iodine abstraction eventually affords the carboiodinated products in good to excellent yields. If TEMPO is added, the cascade provides the cyclized carboaminoxylation products. Running the reaction in the presence of PhTeTePh affords the phenyltellurated cyclized products.

Cascade reactions: A variety of novel cascade reactions can be performed when the known and well-studied radical 5- or 6-exo-cyclization of an aryl diazonium salt is conducted in the presence of alkenes and further optional scavengers (see scheme). Copyri
