Autor: Monique S. J. Simmonds, R. Rubio Gonzalez, R. Rabanedo Clemente, E. M. Martin de la Nava, Alfonso Fernández-Mateos

Publikováno v: Tetrahedron. 61:12264-12274

A diastereoselective synthesis of the model insect antifeedant 29 a CDE molecular fragment of 12-ketoepoxyazadiradione has been achieved in ten steps from indenone 9 in 44% overall yield. Several of the compounds obtained along the synthesis related

Effect of Tether Length on Ti(III)-Mediated Cyclization of Epoxyalkenes and Unsaturated Epoxyketones

Autor: F. Sanz González, R. Rubio Gonzalez, E. M. Martin de la Nava, R. Rabanedo Clemente, L. Mateo Buron, A. Fernandez‐Mateo

Publikováno v: Synlett. 2004:2553-2557

The chemo- and regioselectivity of the radical cyclization induced by titanocene chloride of a series of epoxyalkenes and another of unsaturated epoxyketones are investigated. 5-Exo and 6-exo cyclizations are the main processes with epoxyalkenes. 3-E

Synthesis of C-secoLimonoid Model Insect Antifeedants Related to Ohchinolide and Nimbolidin

Autor: E. M. Martin de la Nava, Alfonso Fernández-Mateos, R. Rubio Gonzalez

Publikováno v: Synthesis. 2002:1728-1734

A concise and stereoselective synthesis of a CDE-seco limonoid related to ohchinolide and nimbolidin was accomplished in eleven and twelve steps, respectively, from α-cyclocitral. Opening of the C ring was first attemptedby a retro-Claisen reactions

The Nazarov cyclization of β-carbonyl-β′-furyl-divinyl ketones and related compounds as induced by perchloric acid

Autor: A. Fernandez Mateos, E. M. Martin de la Nava, R. Rubio Gonzalez

Publikováno v: Tetrahedron. 57:1049-1057

Diluted solutions of perchloric acid and acetic anhydride are introduced as a new catalyst for cationic cyclizations. The influence of the strong acid concentration and the nature of the anhydride have been studied in four types of Nazarov substrates
