Abstract
Seven different 3-aroylflavanones and 3-aroylchromanones were
synthesised from 1,3-propanedione by literature method. They were
subjected to react with different compounds such as (i) thiourea in
pyridine. (ii) pyridine-KOH and (iii) ethanol-KOH medium to give
respective 4-(2-hydroxy-5-methylphenyl)-5-aroyl-6-aryl-2-imino-
6H-2,3-dihydro 1,3-thiazines. The yield is better in case of pyridine-
KOH.
