- Pyrrolo[3,2,1-ij]quinolin-4-one and Pyrrolo[3,2,1-ij]quinolin-6-one
[作者:MCNAB HAMISH; NELSON DAVID J; ROZGOWSKA EMMA J,期刊:Synthesis, 页码:2171-2174 , 文章类型: Article,,卷期:2009年-13]
- The parent pyrrolo[3,2,1-ij]quinolin-4-one and pyrrolo[3,2,1-ij]quinolin-6-one ring systems were made by pyrolysis of appropriate acrylates. In the first case, the cyclisation was effected by flash vacuum pyrolysis (FVP)...
- Diversity-Oriented Synthesis of Functionalized Diaryl Sulfones by Regioselective [3+3] Cyclizations of 1,3-Bis(siloxy)buta-1,3-dienes with 2-(Arylsulfonyl)-3-ethoxy-2-en-1-ones: Scope and Limitations
