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
摘要:
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.
