Flash Vacuum Pyrolysis of 5-(Indol-2- and -3-ylmethylene)-2,2-dimethyl-1,3-dioxane-4,6-diones

Flash vacuum pyrolysis of 5-(indol-2- and -3-ylmethylene)-2,2-dimethyl-1,3-dioxane-4,6-diones results in the initial formation of indolylmethyleneketenes, which generally either lose carbon monoxide to produce ethynylindoles or undergo -sigmatropic shifts, followed by electrocyclic rearrangements, to yield carbazolols or benzindol-5(1H)-one. 5-(Indol-2-ylmethylene)-2,2-dimethyl-1,3-dioxane-4,6-dione and the 3-methylindol-2-yl derivative both yield 3H-pyrroloindol-3-ones via a -sigmatropic rearrangement of the initially formed ketene.
