A one-pot, clean and green procedure is described for the syntheses of new azocine derivativesviaaddition reactions of enaminones with acenaphthoquinone followed by periodic acid-mediated oxidative cleavages of the corresponding vicinal diols. Various derivatives of azocine were prepared and well characterized. The excellent yields, simple synthesis procedure, lack of a need to carry out any tedious work-up and column chromatography, metal-free catalysis, and mild reaction conditions are important features of this protocol.

experimental part, p. 985 - 999 (2009/12/01)
A series of 3-aminocyclohex-2-enones were reacted with indane-1,2,3-trione monohydrate (ninhydrin) yielding 4b,9b-dihydroxyindeno[ 1,2-b]indoles that were deoxygenated to indeno[1,2-b]indoles. Georg Thieme Verlag Stuttgart.
