Copper-Catalyzed Aminooxygenation of N-Allylamidines with PhI(OAc)2
摘要:
A Cu-catalyzed aminoacetoxylation of N-alkenylamidines has been achieved using PhI(OAc)(2) as an oxygen source for synthesis of 4-acetoxymethyl-4,5-dihydroimidazoles, which could be further converted into 2,3-diaminopropanol derivatives using AIH(3) as a reductant.
Cu(II)-Mediated Aminooxygenation of Alkenylimines and Alkenylamidines with TEMPO
摘要:
A method for the synthesis of oxymethyl dihydropyrroles (pyrrolines) and dihydroimidazoles has been developed via Cu(II)-mediated intramolecular aminooxygenation of alkenylimines and alkenylamidines, respectively, with 2,2,6,6-tetramethyl-1-piperidinyloxy radical (TEMPO).
