The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2-Chloro-6-nitrobenzo[d]thiazole(SMILESS: O=[N+](C1=CC=C2N=C(Cl)SC2=C1)[O-],cas:2407-11-6) is researched.Electric Literature of C24H40N4O4Rh2. The article 《Synthesis of a few substituted 3-mercapto-s-triazolo[3,4-b]benzothiazoles》 in relation to this compound, is published in Journal of the Indian Chemical Society. Let’s take a look at the latest research on this compound (cas:2407-11-6).
The benzothiazole I (R = NH2, R1 = NO2) underwent Sandmeyer reaction and the resultant I (R = Cl, R1 = NO2) was treated with H2NNH2.H2O to give I (R = H2NNH, R1 = NO2), which was cyclized with CS2 and the product triazolobenzothiazole II (R1 = NO2, R2 = H) treated with EtI to give II (R1 = NO2, R2 = Et). II (R1 = Cl; R2 = Et, Me) were similarly prepared II had antitumor activity (no data).
