Rh(III)-Catalyzed Tandem Oxidative Olefination-Michael Reactions between Aryl Carboxamides and Alkenes was written by Wang, Fen;Song, Guo-Yong;Li, Xing-Wei. And the article was included in Organic Letters in 2010.Product Details of 491-30-5 This article mentions the following:
Rh(III)-catalyzed oxidative coupling reactions between benzamides or heteroaryl carboxamides and olefins have been developed. The vinylation product can further undergo a Michael reaction leading to γ-lactam in the case of electron-withdrawing olefins. In the experiment, the researchers used many compounds, for example, 1-Hydroxyisoquinoline (cas: 491-30-5Product Details of 491-30-5).
1-Hydroxyisoquinoline (cas: 491-30-5) belongs to isoquinoline derivatives. Being an analog of pyridine, isoquinoline is a weak base, with a pKa of 5.14. The Pomeranz–Fritsch reaction provides a method for the preparation of isoquinoline. This reaction uses a benzaldehyde and aminoacetoaldehyde diethyl acetal, which in an acid medium react to form isoquinoline.Product Details of 491-30-5
