Synthesis and Characterization of a New Chiral Phosphinothiol Ligand Derived from (−)-Menthone and Its Palladium(II) and Platinum(II) Complexes
Autor: Cristobal Segura, Josep Duran, Xavier Fontrodona, Jordi Benet-Buchholz, Julio Real, Alfonso Polo, Nuria Brugat
Publikováno v: Organometallics. 22:3432-3438
The chiral ligand (1R,2S,5R)-1-((diphenylphosphino)methyl)-2-isopropyl-5-methylcyclohexanethiol (4) has been prepared from low-cost commercial (−)-menthone in a three-step enantioselective synthesis. Oxidative addition of 2 equiv of this phosphinot

AM1 study of a substituent transfer by means of a Diels–Alder and retro-Diels–Alder tandem reaction
Autor: Miquel Solà, Cristobal Segura, Miquel Duran, Montserrat Ventura
Publikováno v: J. Chem. Soc., Perkin Trans. 2. :605-608
An AM1 study of two convergent Diels–Alder reactions shows that the formal transfer of a substituent from a dienophile to a diene through a Diels–Alder–retro-Diels–Alder tandem reaction is thermodynamically and kinetically feasible irrespecti

Autor: Cristobal Segura, Montserrat Ventura, Marta Planas, Rosa M. OrtuñTo
Publikováno v: Synthetic Communications. 24:651-658
Two new and easy syntheses of (±)-andirolactone are reported, starting from the major Diels-Alder regio-adduct of 5-methylene-2(5H)-furanone and isoprene.

A quantum chemical AM1 study of a Diels–Alder and retro-Diels–Alder tandem reaction
Autor: Cristobal Segura, Miquel Solà, Montserrat Ventura
Publikováno v: J. Chem. Soc., Perkin Trans. 2. :281-284
An AM1 study on a two convergent Diels–Alder reactions has shown that the formal transfer of an alkoxy substituent from a dienophile to a diene through a Diels–Alder/retro-Diels–Alder tandem reaction is feasible.

Synthesis of 5,5-disubstituted 2(3H)-dihydrofuranones containing side-chain carbonyl functions, and some derivatives
Autor: Montserrat Ventura, Cristobal Segura, Rosa M. Ortuño, Marta Planas, Joan Bassa
Publikováno v: Tetrahedron. 50:8143-8152
Several title compounds containing aldehyde, ketone or unsaturated ester functions in side-chains at C-5 position have been synthesized for the first time. The ability of some of these compounds as precursors in the preparation of polyfunctional cycl

Substituted .gamma.-lactones with vicinal hydrogen atoms. Conformational study by MM2 calculations and coupling constant analysis
Autor: Cristobal Segura, Immaculada Dinarès, Carlos Jaime, Josep Font
Publikováno v: The Journal of Organic Chemistry. 58:154-158
The conformational analysis of substituted γ-lactones with vicinal hydrogen atoms is carried out by the MM2/3JHH tandem. The agreement between experimentally avaible and calculated data is globally correct (rms=1.16 Hz). A general preference for a h
