A convenient and efficient visible-light-induced tandem acylation/cyclization of N-propargylindoles with aryl- or alkyl-substituted acyl oxime esters for the synthesis of 2-acyl-substituted 9H-pyrrolo[1,2-a]indoles under transition-metal-free conditions, which proceeds via nitrogen-centered radical-mediated cleavage of the C-C σ-bond in acyl oxime esters, is established. The aryl or alkyl acyl radicals, which come from acyl oxime esters, attack the C-C triple bonds in N-propargylindoles and then go through intramolecular cyclization/isomerization.

A series of novel ruthenium(II)-cymene complexes (1–9) with substituted α-dicarbonylmonoximes of general formula [Ru(η6-cymene)(L)Cl] (L?=?N,O-chelating bidentate α-dicarbonylmonoxime derivatives) have been synthesized and characterized by elemental analysis, IR, 1H NMR, 13C NMR spectroscopies, and in three cases by single crystal X-ray diffraction analysis. The most effective compound 9 displays remarkable anti-invasion and anti-metastasis properties without apparent cytotoxicity toward three different human cancer cell lines (MCF-7, Hela and HepG2). Further protein level studies suggest that the anti-metastasis activity of the complexes may result from the increasing expression of E-cadherin and reducing expression of Vimentin.

The Beckmann rearrangement of α-oximinoketones gives benzoic acids as chief isolable products. Both first order and second order Beckmann rearrangements have been observed. The occurrence of first order Beckmann rearrangement in these oximinocarbonyl compounds is confirmed through the identification of the products obtained.
