Leiocyclocin C and D, two cyclopeptides from Goniothalamus leiocarpus.

PubMed (2003)

Qing Mu R W Teng C M Li D Z Wang Yangjie Wu

Two new cyclopeptides, leiocyclocin C (1) and D (2), were isolated from the seeds of Goniothalamus leiocarpus (Annonaceae). Their structures were determined as cyclo-(Gly1-Ser-Pro2-Tyr2-Gly2-Tyr1-Pro1-Pro3) and cyclo-(Gly1-Leu-Pro1-Gly2-Phe-Tyr-Pro2), respectively, by means of spectral and chemical methods.

Studies on the Intramolecular Inclusion Complexes of Functionalized Calix[4]arenes with CH₃X (X = CN, NO₂)

Chinese Journal of Chemistry (2002)

Zhixian Zhou Yalin Shi Chenxia Du Yanjun Xing Yangjie Wu

Abstract Two functionalized calix[4]arenes in cone conformation L 2–3 have been synthesized and their intramolecular inclusion complexes (1:1) with organic neutral molecules CH 3 CN and CH 3 NO 2 have been prepared and characterized, respectively. The X‐ray crystallographic analysis shows that L 2 in L 2 ·CH 3 CN. C 2 H 5 OH has C 4 symmestry and L 3 in L 3 .CH 3 NO 2 exhibits C 2 symmestry. The CH‐π aromatic interactions between the CH group of the guest and the phenyl rings of the calix backbond have been proved to be able to stabilize the intramolecular inclusion complexes formed. The interaction is directional, but it is independent of the acidity of the guest. To gain information on CH‐s interactions, suitable geometrical parameters have been calculated from the crystal data of intramolecular inclusion complexes. The results show that L 3 .CH 3 NO 2 with L 3 in C 2 symmestry can also be bound stably in the intramolecular inclusion complex, being consistent with the thermal analysis. The geometrical parameters and the results of the thermal analysis of L 1 .CH 3 CN and L 1 .CH 3 NO 2 were also given and discussed.

Cover Feature: Investigation on Electron Distribution and Synergetic to Enhance Catalytic Activity in Bimetallic Ni(II)/Pd(II) Molecular Monolayer (ChemCatChem 22/2018)

ChemCatChem (2018)

Pingping Huang Ziqian Xue Tiesheng Li Zhongyi Liu Donghui Wei

The Cover Feature shows a GO-supported ordered diimine Ni/Pd bimetallic monolayer as catalyst for cross-coupling reactions. In their Full Paper, P. Huang et al. demonstrate that intermetallic interactions between Ni and Pd centers and synergistic effects play a significant role in enhancing catalytic activity. This facile strategy can be applied to the synthesis of other non-noble-based hybrid nano-catalysts. More information can be found in the Full Paper by P. Huang et al. on page 5141 in Issue 22, 2018 (DOI: 10.1002/cctc.201801350).

Rh(III)-Catalyzed Synthesis of Indazolo[2,3-a]quinolines: Vinylene Carbonate as C1 and C2 Building Blocks

Organic Letters (2022)

Wei Hu Chao Pi Di Hu Xiliang Han Yangjie Wu

A rhodium-catalyzed cyclization of azobenzenes and vinylene carbonate via C-H bond activation to construct indazolo[2,3-a]quinolines has been developed. This protocol offers an efficient method for synthesis of the titled products in good yields with broad functional group tolerance. In this reaction, three C-C bonds and C-N bond are formed in one pot, and vinylene carbonate (VC) acts as C1 and C2 synthons as well as "vinylene transfer" agent and acylation reagent in the construction of target-fused heterocycles. Moreover, the products exhibit favorable fluorescence properties, which indicate their potential application as fluorescent materials and biosensors.
