- Cyclocondensation of Amino-propargyl Silanes
[作者:WANG YIZHONG; READY JOSEPH M,期刊:Organic Letters, 页码:2308-2311 , 文章类型: Article,,卷期:2012年14-9]
- Amino-propargyl silanes condense with carbonyl compounds to form imines and subsequently cyclize to form allenylidene tetrahydroquinolines. The cyclocondensations are catalyzed by a variety of Bronsted acids, among which...
- Synthesis, Properties, and OFET Characteristics of 5,5 '-Di(2-azulenyl)-2,2 '-bithiophene (DAzBT) and 2,5-Di(2-azulenyl)-thieno[3,2-b]thiophene (DAzTT)

- Two azulene-based pi-conjugated systems, 5,5'-di(2-azulenyl)-2,2'-bithiophene and 2,5-di(2-azulenyl)-thieno[3,2-b]thiophene, were constructed via Suzuki-Miyaura cross-coupling reactions. The crystal structures of both re...
- Concise Total Synthesis of (-)-Mersicarpine

- A concise total synthesis of (-)-mersicarpine from a known cyclohexanone was accomplished. The azepinoindole core was constructed by a DIBAL-H-mediated reductive ring-expansion reaction of oxime.
- Simple and Efficient Solid-Phase Preparation of Azido-peptides
[作者:HANSEN MORTEN B; VAN GURP THEODORUS H M; VAN HEST JAN C M; LOWIK DENNIS W P M,期刊:Organic Letters, 页码:2330-2333 , 文章类型: Article,,卷期:2012年14-9]
- A shelf-stable and easily prepared diazotransfer reagent, Imidazole-1-sulfonyl azide hydrochloride, was used to transform the N-terminus of a model peptide on solid phase into an azide moiety. It is demonstrated that thi...
