Catalytic enantioselective 5-hydroxyisoxazolidine synthesis: an asymmetric entry to ?-amino acids

, 2007
The highly chemo- and enantioselective organocatalytic tandem reaction between N-carbamate-protected hydroxylamines and ?,?-unsaturated aldehydes is presented. The reaction represents a unique entry for the asymmetric synthesis of 5-hydroxyisoxazolidines,

Stereoselective total synthesis and enantioselective formal synthesis of the antineoplastic sesquiterpene quinone metachromin A

Journal of the Brazilian Chemical Society, 1999
The first total synthesis of the antineoplastic marine natural product metachromin-A (1) was accomplished through a convergent synthetic approach amenable to the preparation of analogues for biological studies.

Enantioselective Synthesis of the C(1)-C(6?) Subunit of Zaragozic Acid C

Journal of the Brazilian Chemical Society, 1998
Preparation of the C(1)-C(6?) subunit of Zaragozic acid C is described. The C(5?) methyl-bearing stereocenter is installed by rapid, regioselective opening of a phenylcyclopropyl carbinol with Pearlman?s catalyst (1 atm H2) in 2% triflic acid/methanol.

Development of Biocatalysts Based on Lipase B From Candida antarctica Immobilized on Magnetic Poly(Styrene‐Co‐Divinylbenzene) for Application in Esterification Reactions

Journal of Applied Polymer Science, EarlyView.
Magnetic biocatalysts can be recovered from high‐viscosity reaction media, such as those used in esterification, via magnetic attraction, thereby streamlining the bioprocess and reducing costs. This work builds on prior studies by providing additional data on how particle morphology influences immobilization parameters and by further exploring ...
