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.

Diastereoselective anti-aminooxygenation and anti-diamination of alkenes with amidines were enabled by hypervalent iodine(III) reagents such as PhI(OCOR)2 and PhI(NMs2)2, respectively. The present transformation offers diastereochemically pure dihydroimidazoles divergently from E- and Z-alkenes.
