1,3-dipolar cycloadditions of diazoalkanes to activated sulfoxides: influence of Lewis acids.

The Journal of organic chemistry

Ruano JL, Peromingo MT, Alonso M, Fraile A, Martín MR, Tito A.
PMID: 16238331
J Org Chem. 2005 Oct 28;70(22):8942-7. doi: 10.1021/jo051574v.

[reaction: see text] The reactions of diazomethane and diazoethane with (S)-3-p-tolylsulfinylfuran-2(5H)-one (3) and its 4-methyl derivative (4) have been studied. The sulfinyl group was able to completely control the pi-facial selectivity of all these reactions, which decreased when the...

5-Alkoxyfuran-2(5H)-ones and their optically pure 3-p-tolylsulfinyl derivatives, synthetic equivalents of the acyclic esters, react with dipoles generated from allenoates and PPh(3) (Lu reaction), in a completely regioselective, pi-facial selective and endo-selective manner, yielding bicyclic adducts, which are easily converted...

An Analysis of Host Adaptation and Its Relationship with Virulence in Cucumber mosaic virus.

Phytopathology

Sacristán S, Fraile A, Malpica JM, García-Arenal F.
PMID: 18943016
Phytopathology. 2005 Jul;95(7):827-33. doi: 10.1094/PHYTO-95-0827.

ABSTRACT The host range of a pathogen can have special consequences on its evolution and the evolution of its virulence. For generalists, adaptation to different hosts may be conditioned by different trade-offs in the pathogen's life history and be...
