J. Kearns et Mm. Kayser, APPLICATION OF YEAST-CATALYZED REDUCTIONS TO SYNTHESIS OF (2R,3S)-PHENYLISOSERINE, Tetrahedron letters, 35(18), 1994, pp. 2845-2848
A simple synthesis of (2R,3S)-phenylisoserine, a precursor of the C-13
side chain of Taxol(R)(paclitaxel), utilising yeast-catalyzed reducti
on to generate a second chiral centre is reported. This short enantios
elective series of transformations can be readily adapted to large sca
le production of a variety of N-substituted paclitaxel analogues.
