TEMPO-mediated allylic C-H amination with hydrazones
Zhu, Xu,Chiba, Shunsuke
, p. 4567 - 4570 (2014/06/24)
TEMPO-mediated reactions of alkenyl hydrazones afforded azaheterocycles via sp3 C-H allylic amination. The transformation is featured by a sequence of remote allylic H-radical shift and allylic homolytic substitution with hydrazone radicals. This journal is
TEMPO-mediated aliphatic C-H Oxidation with Oximes and hydrazones
Zhu, Xu,Wang, Yi-Feng,Ren, Wei,Zhang, Feng-Lian,Chiba, Shunsuke
supporting information, p. 3214 - 3217 (2013/07/26)
A method for aliphatic C-H bond oxidation of oximes and hydrazones mediated by 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO) has been developed, which enables the concise assembly of substituted isoxazole and pyrazole skeletons.
1,3-Dipolar Cycloadditions, 90. Diphenylnitrilimine and Substituted Butadienes; Substituent Effects and Rate of Cycloaddition
Fliege, Werner,Huisgen, Rolf,Kolbeck, Winfried,Weberndoerfer, Volkmar
, p. 3438 - 3460 (2007/10/02)
1-Substitued butadienes accept diphenylnitrilimine (2) not at the 1,2- but rather at the 3,4-double bond; the regiospecific cycloaddition furnishes 5-substituted 1,3-diphenyl-2-pyrazolines.The relative addition rates, measured in competition experiments,
