Iron-Catalysed Remote C(sp3)-H Azidation of O-Acyl Oximes and N -Acyloxy Imidates

Qian Wang, Jieping Zhu, Ruben Omar Torres Ochoa, Alexandre Julien Florent Leclair

The azido group occupies an important position in modern organic chemistry, broadly used as amine surrogates and as anchors in bioconjugation. Despite their importance, examples of selective direct azidation of inert C(sp3)–H bonds remain limited and often ...

Palladium-Catalyzed Multicomponent Synthesis of Fully Substituted Alkylidene Furanones

Qian Wang, Jieping Zhu, Ruben Omar Torres Ochoa, Angel Renteria Gomez

In the presence of a catalytic amount of Pd(OAc)(2) and XantPhos, the three-component reaction of ynones, imines, and aryl iodides affords fully substituted alkylidene-furan-3(2H)-ones via a sequence of the Mannich reaction followed by chemo- and regiosele ...

Functionalization of remote C(sp3)-H bonds enabled by copper-catalyzed coupling of O-acyloximes with terminal alkynes

Qian Wang, Jieping Zhu, Ruben Omar Torres Ochoa, Zhaodong Li

Transition metal catalyzed Sonogashira cross-coupling of terminal alkynes with aryl(vinyl) (pseudo)halides has been successfully extended to alkyl halides for the synthesis of functionalized internal alkynes. The direct alkynylation of remote unfunctionali ...
