, p. 11340 - 11343 (2018/10/31)
The development of the highly active pincer-type rhodium catalyst 2 for the nucleophilic Meinwald rearrangement of functionalised terminal epoxides into methyl ketones under mild conditions is presented. An excellent regio- and chemoselectivity is obtained for the first time for aryl oxiranes.
NIS-mediated ring-closure/opening cascade reactions of allylamides: An expedient route to oxazolines

An unprecedented NIS-mediated ring-closure/opening cascade reaction of allylamides is developed. The substrates with various functionalities were well tolerated and the scope can be extended to allylic carboxylates. Notably, the resulting iodinated chain
Copper-catalyzed trifluoromethylation and cyclization of aromatic-sulfonyl-group-tethered alkenes for the construction of 1,2-benzothiazinane dioxide type compounds

A multi-talented system: An efficient copper-catalyzed tandem trifluoromethylation/annulation of an electron-deficient aromatic ring has been developed. This method provides a powerful and straightforward way to synthesize trifluoromethylated 1,2-benzothiazinane dioxides under mild conditions (see scheme). The mechanism was investigated by a series of kinetic experiments and isotopic labeling studies.
