Organocatalytic Stereoselective Iodoamination of Alkenes
A new chiral thiohydantoin catalyst is used for the stereoselectiveiodoamination of alkenes. N‐iodosuccinimide as the source of the electrophilic iodine is activated by catalytic amounts of different additives which also influence the regioselectivity of some cyclizations.

A novel palladium-catalyzedintramolecular oxidative aminofluorination of unactivatedalkenes has been developed, in which AgF was used as a key fluorinating reagent and PhI(OPiv)(2) as oxidant. The reaction afforded vicinal fluoroamine products with very high regioselectivity. A Pd(II/IV) catalytic cycle was proposed, and preliminary mechanistic studies indicated that direct reductive elimination

A convenient, metal-free intramolecular aminofluorination of alkenes has been developed. Employing readily available PhI(OPiv)2 and hydrogen fluorideâpyridine in the presence of BF3·OEt2, tosyl-protected pent-4-en-1-amines were converted to 3-F-piperidines in one step in good yields as well as high stereoselectivity.
