Inhibitors of phenylalanine ammonia-lyase: 1-aminobenzylphosphonic acids substituted in the benzene ring
摘要:
Dextrorotatory 1-amino-3',4'-dichlorobenzylphosphonic acid was found to be a potent inhibitor of the plant enzyme phenylalanine ammonia-lyase both in vitro and in vivo from among the ring-substituted 1-aminobenzylphosphonic acids and other analogues of phenylglycine. A structure activity relationship analysis of the results obtained permits predictions on the geometry of the pocket of the enzyme and is a basis in the strategy of better inhibitor synthesis.

intermediates together with easily accessible N-arenesulfonylamino alcohols furnish a broad variety of 1,3-oxazolidines. These are applied as chiral tropos ligands in a titanium-mediated Strecker-type reaction of N-benzhydrylimines. A correlation between the ee values in the product and the diastereomeric ratio concerning the chiral axis of the ligand is made. Those substituents in the ligand which proved

[formula: see text] A novel catalytic enantioselective Strecker synthesis of chiral alpha-amino nitriles and alpha-amino acids is described and analyzed with regard to the possible mechanistic basis for stereoselectivity. Key features of the enantioselective process include (1) the use of the chiral bicyclicguanidine 1 as catalyst and (2) the use of the N-benzhydryl substituent on the imine substrate
Described herein are compounds of formula (I), related compositions, and their use, for example in the formation of α-amino acids or a precursor thereof such as an α-aminonitrile.

The aroylation of carbanions derived from N-benzyl-diphenylmethanimine and N-(diphenylmethyl )-arylmethanimines yields highly substituted 2-aza-buta- 1,3-dienes in which the imino group is conjugated with an enol ester. A similar reaction with N-(diphenylmethyl)-diphenylmethylmethanimine qives the expected iminoketone.
