Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. 1689-64-1, Name is 9H-Fluoren-9-ol, molecular formula is C13H10O, Category: naphthyridines, belongs to naphthyridine compound, is a common compound. In a patnet, author is Win, Khin Myat Noe, once mentioned the new application about 1689-64-1.
In this paper, we report the iodine mediated in situ generation of R-Se-I and further its application towards the construction of pyrano[4,3-b]quinolin-1-one derivatives. The structural elaboration of 1-chloro-8-methyl-3-phenylbenzo[b][1,6]naphthyridine 6 was successfully achieved by Sonogashira, Suzuki coupling and dehalogenation reactions. Finally, the synthesized compounds 4a, 5a, 5b, 6, and 7a-7c were studied for photophysical properties including UV-absorption, fluorescence, and quantum yield studies. The synthesized pyranoquinoline derivatives showed lambda(max), F-max and phi(f) values in the range of 391-447 nm, 436-486 nm and 0.004-0.301, respectively in chloroform solvent.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 1689-64-1, in my other articles. Category: naphthyridines.
