- Fused tetracycles with a benzene or cyclohexadiene core: [2 + 2 + 2] cycloadditions on macrocyclic systems.
[作者:Brun, Sandra;Garcia, Lidia;Gonzalez, Ivan;Torrent, Anna;Dachs, Anna;Pla-Quintana, Anna;Parella, Teodor;Roglans, Anna;,期刊:Chemical Communications, 页码:4339-4341 , 文章类型: 研究论文,,卷期:2008年-36]
- A series of fused tetracycles with a benzene or cyclohexadiene core is satisfactorily prepd. by intramol. [2 + 2 + 2] cycloaddns. of triynic and enediynic macrocycles under RhCl(PPh3)3 catalysis. The enantioselective cy...

- The reaction of enantiomerically pure 2-substituted with Me trifluoromethanesulfonate generated a stable methylaziridinium ion, which was reacted with various external nucleophiles, including nitrile, to yield synthetica...
- Facile fabrication of conducting polymer hydrogels via supramolecular self-assembly.
[作者:Dai, Tingyang;Jiang, Xiujuan;Hua, Shouhu;Wang, Xiaoshu;Lu, Yun;,期刊:Chemical Communications, 页码:4279-4281 , 文章类型: 研究论文,,卷期:2008年-36]
- Conducting polymer hydrogels were obtained via supramol. self-assembly of polymers and multivalent cations. 3,4-Ethylenedioxythiophene (EDOT) monomers are polymd. in PSS aq. soln. under static conditions with Fe3+ ions (...
- Lewis base-catalyzed conjugate reduction and reductive aldol reaction of a,b-unsaturated ketones using trichlorosilane.
[作者:Sugiura, Masaharu;Sato, Norimasa;Kotani, Shunsuke;Nakajima, Makoto;,期刊:Chemical Communications, 页码:4309-4311 , 文章类型: 研究论文,,卷期:2008年-36]
- Lewis bases such as Ph3P=O and HMPA catalyze the 1,4-redn. of a,b-unsatd. ketones with trichlorosilane, and because the 1,2-redn. of aldehydes scarcely proceeded under the conditions, one-pot reductive aldol reactions wi...
