Lakhan, Ram,Ral, Babban J.
, p. 501 - 502 (1986)
Five new 2-methyl-3--4(3H)-quinazolinones have been synthesized.Three of them were tested for their antifungal activity against agricultural fungi by the food poison technique and the activity was compared with that of Dithan M-45.

A facile and sustainable approach for the amination of benzothiazoles with KSeCN using iodine as the catalyst in water has been disclosed under transition-metal free conditions. The reaction proceeded smoothly to afford various primary 2-amino benzothiazoles in up to 96% yield. A series of control experiments were performed, suggesting a ring-opening mechanism was involved via a radical process. This protocol provides efficient synthesis of primary 2-aminobenzothiazoles

Abstract: The condensation of 2-amino-1,3-thiazolium perchlorates and their benzo analogs with trifluoro-acetyl-acetone in acetic acid afforded the corresponding [1,3]thiazolo[3,2-a]pyrimidinium, pyrimido[2,1-b][1,3]benzothiazolium, and naphtho[2′,1′:4,5][1,3]thiazolo[3,2-a]pyrimidinium salts as a single isomer in which the trifluoromethyl group is located in the γ-position with respect to the bridgehead nitrogen atom. The structure of the synthesized compounds was confirmed by 1H NMR spectra and elemental analyses.
