- Towards the Rational Synthesis of Norfullerenes. Controlled Deletion of One Carbon Atom from C60 and Preparation of 2,5,9-Trioxo-1-nor(C60-Ih)[5,6]fullerene C59(O)3 Derivatives.
[作者:Yao, Jiayao;Xiao, Zuo;Gan, Liangbing;Yang, Dazhi;Wang, Zheming;,期刊:Organic Letters, 页码:2003-2006 , 文章类型: 研究论文,,卷期:2008年10-10]
- Norfullerenes are fullerene-like compds. (fulleroids) resulting from partial deletion of fullerene skeleton carbons. The one carbon less norfullerene C59(O)3 derivs. having three carbonyl groups on the rim of the orific...
- Diastereoselective Synthesis of Enantiopure Acyclic b,b'-Disubstituted Vinylsulfoxides.
[作者:Brebion, Franck;Goddard, Jean-Philippe;Fensterbank, Louis;Malacria, Max;,期刊:Organic Letters, 页码:1917-1920 , 文章类型: 研究论文,,卷期:2008年10-10]
- Thermal elimination of sulfenic acid from enantiopure b,b'-disubstituted bis-sulfoxides, e.g. I (R1 = Me2CH, n-Bu, Me3CSiMe2OCH2, Ph, 3-PhOC6H4; R2 = Me, n-Bu; R3 = 4-MeC6H4), allows the stereoselective synthesis of enan...
- Enantiopure 1,5-Diols from Dynamic Kinetic Asymmetric Transformation. Useful Synthetic Intermediates for the Preparation of Chiral Heterocycles.

- Dynamic kinetic asym. transformation (DYKAT) of a series of 1,5-diols has been performed in the presence of Candida antarctica lipase B (CALB), Pseudomonas cepacia lipase II (PS-C II), and ruthenium catalyst. The result...
- Trinorlupeol: A Major Nonsterol Triterpenoid in Arabidopsis.
[作者:Shan, Hui;Wilson, William K.;Phillips, Dereth R.;Bartel, Bonnie;Matsuda, Seiichi P. T.;,期刊:Organic Letters, 页码:1897-1900 , 文章类型: 研究论文,,卷期:2008年10-10]
- We report the structure detn. of 20,29,30-trinorlup-18-en-3b-ol (trinorlupeol (I)) and establish this novel C27 metabolite as a major nonsterol triterpenoid in Arabidopsis thaliana. Trinorlupeol was concd. in cuticular ...
