Aerial Oxygen-Driven Selenocyclization of O-Vinylanilides Mediated by Coupled Fe3+/Fe2+ and I2/I− Redox Cycles
Autor: Hao-Yuan Zhang, Tong-Tong Zeng, Zhen-Biao Xie, Ying-Ying Dong, Cha Ma, Shan-Shan Gong, Qi Sun
Publikováno v: Molecules, Vol 27, Iss 21, p 7386 (2022)
In the past decade, selenocyclization has been extensively exploited for the preparation of a wide range of selenylated heterocycles with versatile activities. Previously, selenium electrophile-based and FeCl3-promoted methods were employed for the s

Photo-Switchable Aggregation-Induced Emission of Bisthienylethene-Dipyrimido[2,1-b][1,3]benzothiazole Triad
Autor: Shan-Shan Gong, Chun-Hong Zheng, Zhen-Zhen Chen, Dong-Zhao Yang, Mei Chi, Shou-Zhi Pu, Qi Sun
Publikováno v: Molecules, Vol 26, Iss 17, p 5382 (2021)
A bisthienylethene-dipyrimido[2,1-b][1,3]benzothiazole (BTE-2PBT) triad has been designed and synthesized based on our recent discovery of PBTs as atypical propeller-shaped novel AIEgens. The triad not only maintains the photochromic properties of BT

Hf(OTf)4 as a Highly Potent Catalyst for the Synthesis of Mannich Bases under Solvent-Free Conditions
Autor: Shuai-Bo Han, Jing-Ying Wei, Xiao-Chong Peng, Rong Liu, Shan-Shan Gong, Qi Sun
Publikováno v: Molecules, Vol 25, Iss 2, p 388 (2020)
Hf(OTf)4 was identified as a highly potent catalyst (0.1−0.5 mol%) for three-component Mannich reaction under solvent-free conditions. Hf(OTf)4-catalyzed Mannich reaction exhibited excellent regioselectivity and diastereoselectivity when alkyl keto

Efficient Synthesis of UDP-Furanoses via 4,5-Dicyanoimidazole(DCI)-Promoted Coupling of Furanosyl-1-Phosphates with Uridine Phosphoropiperidate
Autor: Wei-Jie Chen, Shuai-Bo Han, Zhen-Biao Xie, Hua-Shan Huang, Duo-Hua Jiang, Shan-Shan Gong, Qi Sun
Publikováno v: Molecules, Vol 24, Iss 4, p 655 (2019)
A P(V)-N activation method based on nucleoside phosphoropiperidate/DCI system has been developed for improved synthesis of diverse UDP-furanoses. The reaction conditions including temperature, amount of activator, and reaction time were optimized to

Highly Efficient Synthesis of Substituted 3,4-Dihydropyrimidin-2-(1H)-ones (DHPMs) Catalyzed by Hf(OTf)4: Mechanistic Insights into Reaction Pathways under Metal Lewis Acid Catalysis and Solvent-Free Conditions
Autor: Rui Kong, Shuai-Bo Han, Jing-Ying Wei, Xiao-Chong Peng, Zhen-Biao Xie, Shan-Shan Gong, Qi Sun
Publikováno v: Molecules, Vol 24, Iss 2, p 364 (2019)
In our studies on the catalytic activity of Group IVB transition metal Lewis acids, Hf(OTf)4 was identified as a highly potent catalyst for „one-pot, three-component„ Biginelli reaction. More importantly, it was found that solvent-free conditions
