Heterocyclic analogs of xanthiones: 5,6-fused 3-methyl-1-phenylpyrano[2,3- c]pyrazol-4(1H) thiones - Synthesis and NMR (1H, 13C, 15N) data

Various [5,6]pyrano[2,3-c]pyrazol-4(1H)-thiones were synthesized in high yields by treatment of the corresponding [5,6]pyrano[2,3-c]pyrazol-4(1H)-ones with Lawesson's reagent. Detailed NMR spectroscopic studies were undertaken of the title compounds. Comp
