Tanoury, Gerald J. published the artcilePd-catalyzed aminations of aryltriazolones: effective synthesis of hydroxyitraconazole enantiomers, Formula: C12H16N2O2, the publication is Tetrahedron Letters (1998), 39(38), 6845-6848, database is CAplus.
A palladium-catalyzed amination of triazolone I by piperazine II was used as the key step in an efficient synthesis of highly enantiomerically pure hydroxyitraconazole (III). II (>99% ee) was prepared by reaction of an achiral phenol precursor with the corresponding dioxolyl tosylate (>99% ee).
Tetrahedron Letters published new progress about 67914-60-7. 67914-60-7 belongs to piperazines, auxiliary class Piperazine,Benzene,Phenol,Amide, name is 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone, and the molecular formula is C8H7NO4, Formula: C12H16N2O2.
