Zinc-Mediated Reductive Cyclization of [60]Fullerene with Enones and Subsequent Dehydration under Solvent-Free and Ball-Milling Conditions
Liu, Hong-Wei,Xu, Hui,Shao, Gang,Wang, Guan-Wu
, p. 2625 - 2628 (2019)
The zinc-mediated solvent-free reaction of [60]fullerene with enones and water and the subsequent treatment of a base afford various [60]fullerene-fused cyclopentanols using the ball-milling technique. A plausible reaction mechanism is proposed on the bas
Visible-Light-Driven Reductive (Cyclo)Dimerization of Chalcones over Heterogeneous Carbon Nitride Photocatalyst
Kurpil, Bogdan,Markushyna, Yevheniia,Savateev, Aleksandr
, p. 1531 - 1538 (2019/02/10)
Single-electron reduction of chalcones to the respective radical anions is a useful technique to activate these molecules toward subsequent transformations. Herein, a metal-free photocatalytic version of chalcones reduction in the presence of triethanolam
Reactivity insight into reductive coupling and aldol cyclization of chalcones by visible light photocatalysis
Zhao, Guolei,Yang, Chao,Guo, Lin,Sun, Hongnan,Lin, Run,Xia, Wujiong
experimental part, p. 6302 - 6306 (2012/09/25)
The reductive coupling and cyclization of chalcones to generate cyclopentanol derivatives in up to 84% yield by visible light photoredox catalysis is described. This reaction involves radical anion homocoupling, monoprotonation, and intramolecular cycliza
Intermolecular couplization and cyclization of chalcones promoted by samarium in DMF
Liu, Yongjun,Dai, Ningning,Qi, Yan,Zhang, Shusheng
experimental part, p. 799 - 807 (2009/08/08)
Under mild and neutral conditions, reductive coupling-cyclization of chalcones was promoted by samarium metal with an activator in DMF to afford products in good to excellent yields. The reaction is regioselective over the competitive carbon-carbon double
Aluminium chloride assisted zinc-induced reduction of some α,β-unsaturated ketones
Dey, Sankar P.
scheme or table, p. 761 - 763 (2010/08/19)
Some α,β-unsaturated ketones are reduced to give cyclodimerization products and/or β,β-coupling products in presence of Zn-AlCl3.6H2O-moist THF and aluminium chloride acts as Lewis acid to increase the yield of the products.
Zinc-mediated reductive cyclodimerization of α,β-unsaturated aryl ketones under aqueous conditions
Kumar, Anil,Kumar, Satish,Kapoor, Kamal K.
, p. 621 - 623 (2008/03/12)
Zinc-mediated reductive cyclodimerization of ?,?-unsaturated aryl ketones produces 3,4-trans-diarylcyclopentanols 2 regio- and stereoselectively in good yields in a 1:4 (v/v) mixture of saturated aqueous NH4Cl and tetrahydrofuran at room temper
Cyclodimerisation of α,β-unsaturated ketones promoted by the TiCl4/Sm system
Shi, Daqing,Rong, Liangce,Wang, Juxian,Zhuang, Qiya,Wang, Xiangshan,Tu, Shujiang,Hu, Hongwen
, p. 268 - 269 (2007/10/03)
The cyclodimerisation of α,β-unsaturated ketones induced by the TiCl4/Sm system was studied, cyclopentanol derivatives are prepared in good yields under neutral and mild conditions.
Reductive dicyclization of α, β-unsaturated ketones promoted by Sm and catalysed by HgCl2
Zhang, Jiming,Zhang, Yongmin
, p. 1768 - 1770 (2007/10/03)
Reductive dicyclization of α, β-unsaturated ketones promoted by Sm and catalysed by HgCl2 was studied under mild and neutral conditions. The reaction is regioselective over the competitive carbon-carbon double bond reduction and stereocontrolle
Cp2TiCl-mediated selective reduction of α,β-unsaturated ketones
Moisan, Lionel,Hardouin, Christophe,Rousseau, Bernard,Doris, Eric
, p. 2013 - 2015 (2007/10/03)
A mild method for the selective reduction of α,β-unsaturated ketones is reported. The process described herein involves, as the active species, the low-valent titanium complex Cp2TiCl.
