Embodiments provide, among other compounds, a family of compounds that can be used as therapeutic anti-cancer agents, methods for using such compounds to treat cancer, and methods of making such compounds.
Bistrifluoromethanesulfonimide has been used to catalyze C-C bondforming reactions such as Friedel-Crafts, Mukaiyama, 1,2-addition and 1,4-addition as well as C-glycosidation reactions.

The primary alkoxyl radical generated by reaction of 1-(2-hydroxyethyl)-glycosides with (diacetoxyiodo)benzene (DIB) and iodine can undergo regioselective intramolecular hydrogen abstraction (IHA) reactions to furnish four different dioxabicyclic systems derived from carbohydrates. The results strongly suggest that the regiocontrol and feasibility of the cyclisation are dependant not only on geometric
Intramolecular Hydrogen Abstraction Promoted by Amidyl Radicals. Evidence for Electronic Factors in the Nucleophilic Cyclization of Ambident Amides to Oxocarbenium Ions
A tandem 1,5-hydrogen atom transfer/radical oxidation/nucleophilic cyclization mechanism is proposed for the intramolecular hydrogenabstraction reaction promoted for primary carboxamidyl radicals. The electron-withdrawing capacity of the C-5 substituent can switch the reaction to give exclusively bicyclic spirolactams (6-oxa-1-azaspiro[4.5]decan-2-one) when R(1) = H or spirolactones (1,6-dioxaspiro[4
A radicalallylationreaction without tin: The xanthate group in aliphatic xanthates can be replaced by an allyl unit [Eq. (a)]. This radical chain reaction is propagated by ethyl radicals generated by extrusion of sulfur dioxide from ethanesulfonyl radicals, which are themselves derived from allyl ethyl sulfone.
