Isothiazole, cas is 288-16-4, it is a common heterocyclic compound, the isothiazole compound, its synthesis route is as follows.,288-16-4
EXAMPLE 15 6-Cyano-1-hydroxy-1-(5-isothiazolyl)-1,2,3,4-tetrahydronaphthalene Analogously to Example 12, the crude title compound is obtained starting from 353 mg of isothiazole, 0.632 ml of diisopropylamine, 3 ml of 1.6M n-butyllithium in hexane and 546 mg of 6-cyano-1-tetralone in 38 ml of THF. It is purified by column chromatography (SiO2, hexane/ethyl acetate 4:1) and crystallisation from hexane; m.p. 182-184; 1 H-NMR (d6 -DMSO): delta(ppm)=1.76 and 1.97 (2m,4H), 2.9 (t,2H), 6.65 (s,1H), 6.93 (d,1H), 7.37 (dd,1H), 7.59 (dd,1H), 7.7 (d,1H), 8.39 (d,1H).
With the rapid development of chemical substances, we look forward to future research findings about Isothiazole
