Room temperature synthesis of isoquino[2,1-a][3,1]oxazine and isoquino[2,1-a]pyrimidine derivatives via visible light photoredox catalysis was written by Xuan, Jun;Feng, Zhu-Jia;Duan, Shu-Wen;Xiao, Wen-Jing. And the article was included in RSC Advances in 2012.HPLC of Formula: 207451-81-8 This article mentions the following:
A novel and efficient construction of isoquino[2,1-a][3,1]oxazine and isoquino[2,1-a]pyrimidine frameworks has been realized by means of visible light photocatalytic reactions using air as the oxidant at room temperature This strategy offers a direct and rapid access to two kinds of biol. important fused heterocycles in good to excellent yields. In the experiment, the researchers used many compounds, for example, 7-Methyl-1,2,3,4-tetrahydroisoquinoline (cas: 207451-81-8HPLC of Formula: 207451-81-8).
7-Methyl-1,2,3,4-tetrahydroisoquinoline (cas: 207451-81-8) belongs to tetrahydroisoquinoline derivatives. Tetrahydroisoquinoline motif is often present in natural products with a broad range of biological and pharmacological activities. Among them, 1-substituted tetrahydroisoquinolines are privileged scaffolds in drugs and pharmaceuticals. An oxidative C1 arylation of tetrahydroisoquinolines with aryl Grignard reagents is mediated by diethyl azodicarboxylate (DEAD). This C-H activation under metal-free conditions delivers target compounds, including some naturally occurring alkaloids, in good yields.HPLC of Formula: 207451-81-8
