Herein described are the first efficient nitrogen-atom transfer reactions mediated by iron N, N'-dimethyl- N, N'-bis(2-pyridinylmethyl)cyclohexane-1,2-diamine- (MCP-) and 2-({1-[(pyridin-2-ylmethyl)pyrrolidin-2-yl]pyrrolidin-1-yl}methyl)pyridine-type

Alcohol-anchored sulfamate esters guide the alkylation of tertiary and secondary aliphatic C(3)–H bonds. The transformation proceeds directly from N–H bonds with a catalytic oxidant, a contrast to prior methods which have required pre-oxidation o

Owing to the pervasiveness of hydroxyl groups in natural isolates, alcohol derivatives are alluring directing groups. Herein, an alcohol-derived sulfamate ester guides the light-initiated xanthylation of primary, secondary, or tertiary centers. This

A general approach to access sulfamate esters through preparation of sulfamic acid salts, subsequent activation with triphenylphosphonium ditriflate, and nucleophilic trapping is disclosed. The method proceeds in modest to excellent yields to incorpo

Two 1,2-dihydro-2,2,4-trimethylquinoline derivatives and two methyl 3,4,5-trimethoxybenzoate derivatives have been synthesized and their crystal structure determined by X-ray single crystal diffraction. Both methyl 3,4,5-trimethoxybenzoate derivative

An iodine-catalyzed direct cycloalkenylation of dihydroquinolines and arylamines has been developed. This method consists of a Friedel–Crafts reaction between dihydroquinolines (or arylamines) and cyclic ketones in which the double bond is selectiv
