متن کاملApproaches to the asymmetric synthesis of unusual amino acids.
This chapter will focus on critically evaluating some selected new methods to achieve the asymmetric synthesis of a-amino acids. It is not meant to be comprehensive, but rather to reflect some of the possibilities opening up in this area. The study of a-amino acids is one of fundamental importance to many areas of chemistry and its relation to molecular biology. Nature only utilizes 20 amino ac...
متن کاملα-Vinylic amino acids: occurrence, asymmetric synthesis, and biochemical mechanisms
This report presents an overview of the family of naturally occurring “vinylic” amino acids, namely those that feature a C–C double bond directly attached to the α-carbon, along the side chain. Strategies that have been brought to bear on the stereocontrolled synthesis of these olefi nic amino acids are surveyed. The mechanistic diversity by which such “vinylic triggers” can be actuated in a PL...
متن کاملSynthesis of quaternary α-methyl α-amino acids by asymmetric alkylation of pseudoephenamine alaninamide pivaldimine.
The utility of pseudoephenamine as a chiral auxiliary for the alkylative construction of quaternary α-methyl α-amino acids is demonstrated. The method is notable for the high diastereoselectivities of the alkylation reactions, for its versatility with respect to electrophilic substrate partners, and for its mild hydrolysis conditions, which provide α-amino acids without salt contaminants. Alter...
متن کاملDirect Catalytic Asymmetric Amination of Aldehydes: Synthesis of Evans Oxazolidinones and a-Amino Acids
Background The catalysis of reactions with organic molecules void of transition metals has lately assumed a prominent role in asymmetric synthesis. Among different catalysts, proline, an abundant, inexpensive amino acid available in both enantiomeric forms, has emerged as arguably the most practical and versatile. The simultaneous presence of a carboxylic acid and amine bestows a unique bifunct...
