哥们,你怎么回事?
你是不是在研究所读研或博呀?
我帮你找了两篇,发过去了。
剩下一片不知道在那个数据库里,也就没找,需要的话你把数据库告诉我
我帮你找找看

Synthesis of 6-functionalized tricyclodecadienones using Barton's radical decarboxylation reaction. Generation of tricyclo[5.2.1.02,6]decatrienone, a norbornene annulated cyclopentadienone. Zhu, Jie; Klunder, Antonius J. H.; Zwanenburg, Binne. Dep. Org. Chem., Univ. Nijmegen, Nijmegen, Neth. Tetrahedron (1995), 51(17), 5099-116. Publisher: Elsevier, CODEN: TETRAB ISSN: 0040-4020. Journal written in English. CAN 123:256208 AN 1995:550632 CAPLUS

Abstract

An effective synthesis of 6-functionalized endo-tricyclo[5.2.1.02,6]deca-4,8-dien-3-ones (7) starting from the carboxylic acid has been accomplished, whereby the chem. scope of the tricyclodecadienone system as a synthetic equiv. of cyclopentadienone has been expanded. Bridgehead bromide (7d) gives upon treatment with base access to norbornene-annulated cyclopentadienone which rapidly undergoes either regioselective nucleophilic addn. or Diels-Alder cyclization, depending on the applied reaction conditions. 第一篇找的这个啊,你可写错了啊

第二篇是这个吗New directions for the Morita-Baylis-Hillman reaction; homologous aldol adducts via epoxide opening. Krafft, Marie E.; Wright, James A. Department of Chemistry and Biochemistry, Florida State University, Tallahassee, FL, USA. Chemical Communications (Cambridge, United Kingdom) (2006), (28), 2977-2979. Publisher: Royal Society of Chemistry, CODEN: CHCOFS ISSN: 1359-7345. Journal written in English. CAN 145:292782 AN 2006:686324 CAPLUS

Abstract

Under trialkylphosphine-catalyzed Morita-Baylis-Hillman reaction conditions, epoxides react with enones to give rise to homologous aldol adducts. For example, 92 % (2-benzoyl-4,4-dimethylcyclopent-2-enyl)methanol was obtained from 2-((3E)-2,2-dimethyl-5-oxo-5-phenyl-3-pentenyl)oxirane.

O-Arylation versus C-Arylation: Copper-Catalyzed Intramolecular Coupling of Aryl Bromides with 1,3-Dicarbonyls. Fang, Yewen; Li, Chaozhong. Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, Shanghai, Peop. Rep. China. Journal of Organic Chemistry (2006), 71(17), 6427-6431. Publisher: American Chemical Society, CODEN: JOCEAH ISSN: 0022-3263. Journal written in English. CAN 145:314769 AN 2006:725299 CAPLUS

Abstract

The Cu-catalyzed intramol. couplings of aryl bromides with 1,3-dicarbonyls via a six-membered ring closure were examd. With CuI (10 mol %) as the catalyst, N,N'-dimethylethylenediamine as the ligand, and Cs2CO3 as the base, the reactions of a-(2-bromobenzyl) b-keto esters in refluxing THF gave the corresponding 4H-1-benzopyrans in high yields via O-arylation. Whereas, reactions of d-(2-bromophenyl) b-keto esters in refluxing dioxane gave 3,4-dihydronaphthalen-2(1H)-ones via C-arylation.
