THE SPATIAL CONFIGURATION OF a-AMINO-p- HYDROXY -n-BUTYRIC ACID *
Several months ago McCoy, Meyer, and Rose (1935) described the isolation and identification of cr-amino+-hydroxy-n-butyric acid as a cleavage product of proteins, and demonstrated that the new amino acid is an indispensable component of the diet. Since that time attention has been directed to the determination of the spatial configuration of the compound. It is the purpose of the present paper ...
متن کاملβ-Amino-n-butyric Acid Regulates Seedling Growth and Disease Resistance of Kimchi Cabbage
Non-protein amino acid, β-amino-n-butyric acid (BABA), has been involved in diverse physiological processes including seedling growth, stress tolerance and disease resistance of many plant species. In the current study, treatment of kimchi cabbage seedlings with BABA significantly reduced primary root elongation and cotyledon development in a dose-dependent manner, which adverse effects were si...
متن کاملSYNTHESIS OF a-AMINO-p-HYDROXY-n-BUTYRIC ACIDS VII. AN IMPROVED SYNTHESIS OF DL-ALLOTHREONINE
Several methods are available for the synthesis of DL-threonine (l-3). However, each of these involves the separation of threonine from a mixture containing varying proportions of the isomeric allothreonine. Recently it has been reported that derivatives of rm-allothreonine may be converted to DL-threonine in excellent yields (3-5). These developments make the preparation of nn-allothreonine of...
متن کاملA highly enantioselective four-component reaction for the efficient construction of chiral β-hydroxy-α-amino acid derivatives.
An enantioselective four-component reaction of a diazoketone, water, an aniline and ethyl glyoxylate in the presence of catalytic Rh2(OAc)4 and a chiral Brønsted acid was developed to efficiently produce β-hydroxy-α-amino acid derivatives in good yields with high diastereoselectivity and enantioselectivity.
متن کاملDevelopment of ProPhenol Ligands for the Diastereo- and Enantioselective Synthesis of β-Hydroxy-α-amino Esters
A zinc-ProPhenol-catalyzed direct asymmetric aldol reaction between glycine Schiff bases and aldehydes is reported. The design and synthesis of new ProPhenol ligands bearing 2,5-trans-disubstituted pyrrolidines was essential for the success of this process. The transformation operates at room temperature and affords syn β-hydroxy-α-amino esters in high yields with good to excellent levels of di...
