- Diastereoselective Synthesis of a-Tocopherol: A New Concept for the Formation of Chromanols.
[作者：Chapelat, Julien;Buss, Axel;Chougnet, Antoinette;Woggon, Wolf-D.;,期刊：Organic Letters, 页码：5123-5126 , 文章类型： 研究论文，,卷期：2008年10-22]
- A diastereoselective synthesis of a-tocopherol (93% de) was achieved via two key steps, (i) a highly diastereoselective Shi epoxidn. of trisubstituted alkene I and (ii) an acid supported, "anti-Baldwin" epoxide ring open...
- Siloxacyclopentenes as Dienophile-Linked Directing Groups in Intramolecular Diels-Alder Reactions.
[作者：Halvorsen, Geoff T.;Roush, William R.;,期刊：Organic Letters, 页码：5313-5316 , 文章类型： 研究论文，,卷期：2008年10-22]
- The synthesis and intramol. Diels-Alder reactions of trienes, I (n = 1, 2, R = Ph, 2-furyl, CH(OCH2)2) with a siloxacyclopentene-constrained dienophile are described. These reactions provide the primary cycloadducts 7 a...
- Palladium-Catalyzed Synthesis of 2-Substituted Benzothiazoles via a C-H Functionalization/Intramolecular C-S Bond Formation Process.

- Catalytic synthesis of 2-substituted benzothiazoles, e.g., I, from thiobenzanilides was achieved in the presence of a palladium catalyst through C-H functionalization/C-S bond formation. This method features the use of ...
- Design and Synthesis of Stereochemically Defined Novel Spirocyclic P2-Ligands for HIV-1 Protease Inhibitors.
[作者：Ghosh, Arun K.;Chapsal, Bruno D.;Baldridge, Abigail;Ide, Kazuhiko;Koh, Yashiro;Mitsuya, Hiroaki;,期刊：Organic Letters, 页码：5135-5138 , 文章类型： 研究论文，,卷期：2008年10-22]
- The synthesis of a series of stereochem. defined spirocyclic compds., e.g. I, and their use as novel P2-ligands for HIV-1 protease inhibitors are described. The bicyclic core of the ligands was synthesized by an efficie...
- Cycloreversion of Azetidines via Oxidative Electron Transfer.
[作者：Steady-State and Time-Resolved Studies. Andreu, Inmaculada;Delgado, Julio;Espinos, Amparo;Perez-Ruiz, Raul;Jimenez, M. Consuelo;Miranda, Miguel A.;,期刊：Organic Letters, 页码：5207-5210 , 文章类型： 研究论文，,卷期：2008年10-22]
- Cycloreversion of cis- and trans-1,2,3-triphenylazetidine (c-2 and t-2) is achieved by electron transfer to tris(4-bromophenyl)aminium radical cation (5?). Stepwise C-N and C-C bond cleavage of azetidine radical cations...
- Crystallographic Evidence of an Unusual, Pentagon-Shaped Folding Pattern in a Circular Aromatic Pentamer.
[作者：Qin, Bo;Chen, Xiuying;Fang, Xiao;Shu, Yingying;Yip, Yeow Kwan;Yan, Yan;Pan, Siyan;Ong, Wei Qiang;Ren, Changliang;Su, Haibin;Zeng, Huaqiang;,期刊：Organic Letters, 页码：5127-5130 , 文章类型： 研究论文，,卷期：2008年10-22]
- conformational flexibility of an oligomeric backbone. Cyclization of a rigidified, suitably sized oligomer led to a circular arom. pentamer. Its crystal structure detd. by X-ray crystallog. reveals a pseudo five-fold s...
