Practical Stereoselective Synthesis of β-Branched α-Amino Acids through Efficient Kinetic Resolution in the Phase-Transfer-Catalyzed Asymmetric Alkylations
Phase-transfer-catalyzedalkylation of glycinate Schiff base with racemic secondary alkyl halides proceeded with excellent levels of syn- and enantioselectivities under the influence of chiral quaternary ammonium bromide 1d and 18-crown-6. The alkylation product can be selectively converted to the corresponding anti isomer, allowing the preparation of all the stereoisomers of beta-alkyl-alpha-amino

The disclosure herein provides compounds and pharmaceutical compositions for the modulation of IL-17A useful for the treatment of inflammatory conditions, such as psoriasis.
The bis-phosphetanes 1 and 2 have been used as chiral ligands in the rhodium-catalysed hydrogenations of dehydroamino acid derivatives. An unusual increase of the optical yields at high hydrogen pressures has been noticed. Mechanistic implications are discussed. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
