FORMAMIDE AS A SUPERIOR NITROGEN NUCLEOPHILE IN PALLADIUM(II) MEDIATED SYNTHESIS OF IMIDAZOLIDINES

[摘要] Formamides emerge as superior nitrogen nucleophiles in palladium(II) catalyzed oxidative 5-exo cyclizations of formaldehyde aminals derived from N-Boc protected allylic amines. The product imidazolidines are readily transformed into protected vicinal diamines
