The present invention relates to compounds of Formula (I) inhibiting indoleamine 2,3-dioxygenase (IDO) and/or tryptophan 2,3-dioxygenase (TDO) enzymes. Further, their synthesis and their use as medicaments in the treatment of inter alia cancer is disclosed.
CHIRAL (S)-(+) 1-SUBSTITUTED ARYL-4-(1-PHENYL) ETHYLFORMAMIDO-5-AMINO-1, 2, 3-TRIAZOLE: A NEW CLASS OF CHIRAL LIGANDS FOR THE SILVER(I)-PROMOTED ENANTIOSELECTIVE ALLYLATION OF ALDEHYDES
BINAP-silver (I) complex as a catalyst (3). To the best of our knowledge, this is the f e w case using a chiral silver (I) complex in a catalytic asymmetric reaction. This interesting result prompted us to design and synthesize other chiral ligands which are suitable for making chiral silver(I) complexes for catalytic asymmetric reactions. We wanted to try some chiral ligands containing a nitrogen atom
Some new 1-aryl-4-ethoxycarbonyl-5-dimethylaminomethyleneamino- 1,2,3-triazoles were first prepared from 1-aryl-4-ethoxycarbonyl-5-amino-1,2,3-triazoles and N,N-dimethylformamide in the presence of phosphorus oxychloride under mild condition in excellent yields. Their structures were characterized by IR, H-1 NMR, MS, and elemental analysis, and their inhibiting effects on various bacteria were also screened.
Chiral (S)‐(+) 1‐Substituted Aryl‐4‐(1‐phenyl) Ethylformamido‐5‐amino‐1,2,3‐triazole: A New Class of Chiral Ligands for the Silver(I)‐Promoted Enantioselective Allylation of Aldehydes
Some novel chiral ligands, (S)-(+) 1-substituted aryl-4-(1-phenyl) ethylformamido-5-amino-1,2,3-triazoles, were prepared starting from 1-substituted aryl-4-ethoxycarbonyl-5-amino-1,2,3-triazoles and other reagents. They were used as catalytic chiral ligands in the silver (I)-promoted enantioselective allylation reaction of aldehydes with allyltributyltin.
