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.

An efficient, inexpensive, environmentally friendly and high yield one-pot route to new spiro[indolo-3,10′-indeno [1,2-b]quinolin]-trione derivatives has been developed, involving three-component reaction of enaminones, N-substituted isatins and Indane-1,3-dione catalyzed by FeCl3. The approach to this spiro-heterocycle is noteworthy because it results in the formation of three new σ (two C-C and one C-N) bonds in a single operation, leading to the construction of novel spiro skeleton. This method works on a large scale in excellent yields.
Palladium-catalyzed coupling of vinylogous amides with aryl halides: Applications to the synthesis of heterocycles

, p. 1109 - 1112 (2007/10/03)
Described herein is the first example of the palladium-catalyzed coupling of vinylogous amides with aryl bromides and chlorides. The scope of this reaction with respect to the aryl component is investigated. Additionally, a tandem reaction sequence in which the above coupling is followed by an intramolecular Heck reaction is presented. These reactions can be applied to high-yielding, one-pot syntheses of nitrogen-containing heterocycles.
