Application In Synthesis of 5-Fluoroindoline. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5-Fluoroindoline, is researched, Molecular C8H8FN, CAS is 2343-22-8, about One-Pot Parallel Synthesis of 5-(Dialkylamino)tetrazoles. Author is Savych, Olena; Kuchkovska, Yuliya O.; Bogolyubsky, Andrey V.; Konovets, Anzhelika I.; Gubina, Kateryna E.; Pipko, Sergey E.; Zhemera, Anton V.; Grishchenko, Alexander V.; Khomenko, Dmytro N.; Brovarets, Volodymyr S.; Doroschuk, Roman; Moroz, Yurii S.; Grygorenko, Oleksandr O..
Two protocols for the combinatorial synthesis of 5-(dialkylamino)tetrazoles were developed. The best success rate (67%) was shown by the method that used primary and secondary amines, 2,2,2-trifluoroethylthiocarbamate, and sodium azide as the starting reagents. The key steps included the formation of unsym. thiourea, subsequent alkylation with 1,3-propane sultone and cyclization with azide anion. A 559-member aminotetrazole library was synthesized by this approach; the overall readily accessible (REAL) chem. space covered by the method exceeded 7 million feasible compounds
