Page/Page column 9; 13; 14, (2012/09/21)
A method for preparing(2R,3S)-2-benzyloxy-3-tert-butoxy-carbonylamino-3-phenylpropionic acid of formula (I) is provided, and a method for purifying and isolating the compound is also provided. The method uses inexpensive, non-hazardous and easily available reagents and results in better yields and purity.

Page/Page column 17, (2010/04/06)
A process for stereoselective synthesis of a β-phenylisoserine comprises reacting a carbonyl imine R-C=N-CO-OR1 with a protected α- oxyaldehyde X1O-CH2CHO in the presence of a chiral amine catalyst and oxidizing aldehyde s
Catalytic asymmetric synthesis of the docetaxel (Taxotere) side chain: organocatalytic highly enantioselective synthesis of esterification-ready α-hydroxy-β-amino acids

body text, p. 6631 - 6634 (2009/04/06)
A highly enantioselective catalytic route to protected β-amino-α-hydroxy acids, such as the side chain of Taxotere, is presented. The organocatalytic asymmetric reactions between unmodified protected α-oxyaldehydes and N-Boc-protected aryl imines give the corresponding compound with up to >19:1 dr and 99-99% ee.

, (2008/06/13)
This invention relates to a method of stereoselective preparation of a derivative of β-phenylisoserine of formula (I) by the action of an N-carbonyl-benzylimine of formula (II) on an optically active amide of a protected hydroxyacetic acid of formula (III
Highly stereocontrolled and efficient preparation of the protected, esterification-ready docetaxel (Taxotere) side chain

, p. 1238 - 1240 (2007/10/02)
A high-yield synthesis of the p-methoxybenzylidene-protected docetaxel (Taxotere) side chain, a useful derivative for efficient, epimerization-free esterification of the 7,10-bis[(trichloroethoxy)carbonyl] derivative of 10-desacetylbaccatin III for the preparation of docetaxel, has been effected; the C-4 and C-5 stereocenters of the 1,3-oxazolidine are generated with complete (≥99%) stereocontrol whereas that at C-2 is produced with 96% selectivity.
