Thorat, Raviraj Ananda published the artcileSynthesis of Chiral-Substituted 2-Aryl-ferrocenes by the Catellani Reaction, Product Details of C6H3ClFI, the main research area is palladium catalyzed three component coupling iodoarene acrylate iodoferrocencarboxamide; chiral aryl ferroceneamide preparation.
A Pd-catalyzed and norbornene-mediated methodol. was developed for the synthesis of chiral 2-aryl-ferroceneamides from chiral 2-iodo-N,N-diisopropylferrocencarboxamide, iodoarenes, and alkenes using a JohnPhos ligand and K carbonate as a base in DMF at 105°. The developed three-component coupling protocol allows the compatibility of electron-withdrawing fluoro, chloro, ester, and nitro and electron-donating Me, methoxy, dimethoxy, benzyl ether-substituted iodo-benzenes, other iodoarenes, such as iodo-naphthalene, heteroarenes, such as iodothiophene, and terminating substrates, such as Me, Et, tert-Bu acrylates, and substituted styrenes with 2-iodo-N,N-diisopropylferrocencarboxamide. Also, the developed three-component Catellani method proceeded with the retention of the configuration of the planar chiral ferrocene, which depends on the role of the participating C-I bond in ferrocene. Consequently, the developed protocol enabled the formation of densely substituted chiral 2-aryl ferroceneamides, exhibiting good to excellent enantioselectivity. The conversion of an ester of the synthesized chiral 2-aryl ferroceneamides also was carried out to further accommodate the easily expendable acid and alc. functionalities.
