Abstract
The reaction of 2-[p-(N,N'-dimethylaminophenyl)]-naphtho [2,1-b]-2,3-d ihydropyran-4-one L with 2-mercaptoaniline 2 has been investigated The yet unreported 6-(p-N,N'-dimethylaminophenyl)naptho [2,1-b]-pyrano-[3 ,4-b] benzo-(4H)-1,4-thiazine 3 system has been synthesised and charac terised on the basis of spectral and analytical data. A novel synthest ic route to naphtho (2,1-b)-pyrano (4,3-c) pyridazin-3-one 6 is report ed.
