1,3-Carbothiolation of 4-(Trifluoromethyl)-p-Quinols: A New Access to Functionalized (Trifluoromethyl)arenes
摘要:
A new strategy, the 1,3-carbothiolation/aromatization, for the synthesis of functionalized (trifluoromethyl)arenes has been developed that enables the regioselective introduction of two different functional groups onto an "aromatic ring" in the meta-position to each other in a single step.

A novel multicomponent reaction of p-(trifluoromethyl)- p-quinolsilyl ethers, ketones, and nitriles was developed for the efficient synthesis of p-trifluoromethylated N-benzylamides. The key step of the reaction involves the formation of an unstable condensation precursor in situ generated form the condensation of p-(trifluoromethyl)- p-quinolsilyl ethers with ketones. This work provides a significant

A series of tunable iminiumions, generated in situ by the condensation of 4-trifluoromethyl-p-quinols with cyclic amines, can lead to the divergent synthesis of trifluoromethylated arylamines in a single step via redox-neutral isomerization. The direct α- and β-functionalization of saturated amines can be achieved regioselectively under mild conditions.
