- Novel Double Functional Group Transformation: 'One-flask' Conversion of 1-Nitrocycloalkenes to Terminally Unsaturated Nitriles
-
A new method has been developed for the conversion of 1-nitrocycloalkenes to terminally unsaturated nitriles in one flask by use of Me3SiCH2MgCl (1.8 equiv.) and PCl3 (2.5 equiv.) in tetrahydrofuran.

- METHOD FOR PRODUCING HIGH PURITY TERMINAL OLEFIN COMPOUND
-
An industrially advantageous method for producing a high purity terminal olefin is disclosed, comprising the steps of (a) contacting a mixture comprising a terminal olefin represented by formula (1): and one or more corresponding internal olefins as impurities, with a brominating agent in the presence of water or an alcohol, to convert the internal olefin(s) to compound(s) having a higher boiling point than the terminal olefin; and (b) purifying the terminal olefin by distillation from the reaction mixture.

- Combination of RCM and the Pauson-Khand reaction: One-step synthesis of tricyclic structures
-
The combination of ring-closing metathesis (RCM) followed by an intramolecular Pauson-Khand reaction gives direct entry to tricyclic compounds. The RCM was carried out on a hexacarbonylcobalt-complexed alkyne, this complex acting as a protecting group against enyne metathesis. The procedure was studied for dienynes containing heteroatoms and allows the building of [6,5,5] and [7,5,5] tricyclic systems. The feasibility of the process depends strongly on the nature of the substrate. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

- Reductive decyanation of α-cyano and α-alkoxycarbonyl substituted nitriles promoted by samarium(II) iodide
-
Decyanation of geminal dinitriles and α-alkoxycarbonyl substituted nitriles promoted by samarium(II) iodide has been efficiently achieved. This method has advantages over the previously known radical route using tin hydride with respect to applicable substrates and the reaction temperature employed. This decyanation could broaden the synthetic applicability of the nitrile derivatives.
