Conceptual design of 1000 m scale steel-UHPFRC composite truss arch bridge

Jieping Zhu, Ping Zhu, Xiujiang Shen

Excessive self-weight and difficulty in construction are the main issues confronted by super-long-span arch bridges. To address these issues, a conceptual design of steel-ultra-high performance fibre-reinforced concrete (UHPFRC) composite truss arch bridge ...

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 ...

Copper‐Catalyzed Aza‐Sonogashira Cross‐Coupling to Ynimines: Development and Application to the Synthesis of Heterocycles

Jieping Zhu, Qiang Wang, Rémi Hugo Lavernhe

Nitrogen substituted alkynes such as ynamines and ynamides are versatile synthetic building blocks in organic chemistry. Ynimines bearing additional nucleophilic and electrophilic centers relative to ynamines and ynamides are expected to have high syntheti ...

Catalytic Enantioselective Aminopalladation–Heck Cascade

Qian Wang, Jieping Zhu, Hua Wu, Jian Cao, Yuping He

Domino processes initiated by intramolecular nucleopalladation of alkynes have been developed into powerful synthetic tools for the synthesis of functionalized heterocycles. However, a catalytic enantioselective version of this class of reactions remains s ...

Photoredox Catalytic Three-Component Amidoazidation of 1,3-Dienes

Qian Wang, Jieping Zhu, Dan Forster, Weisi Guo

In spite of the obvious synthetic potential of functionalized allylic azides, only limited synthetic routes have been developed. We report herein a three-component 1,2-amidoazidation of 1,3-dienes. In the presence of fac-Ir(ppy)(3) under blue LED irradiati ...

Fused N‐Heterocycles with Contiguous Stereogenic Centers Accessed by an Asymmetric Catalytic Cascade Reaction of Tertiary Enamides

Jieping Zhu, Shuo Tong

We report in this article a cascade reaction strategy for the synthesis of complex N-heterocyclic compounds with contiguous and tetrasubstituted stereogenic carbons. Under the sequential catalysis of a chiral binol–Ti complex and BF3, cyclopentanone-derive ...
