| Abstract: | A simple and convenient
procedure for the synthesis of 3-[2-(3-methyl-4,5-dihydro-furo[2,3-c]pyrazol-1-yl)-thiazol-4-yl]-chromen-2-ones
4a-f is described through anhydrous zinc chloride-catalyzed one pot
condensation of 3-(2-bromoacetyl)coumarin, thiosemicarbazide and
2-acetylbutyrolactone in good yields. The title compounds 4a-f are also
synthesized via an alternative
procedure. |
