An aryl radical activation strategy has been developed that can engage unactivated alkyliodides in copper-catalyzed Negishi-type cross-coupling reactions. The strategy is based on the largely overlooked yet highly efficient reactivity of aryl radicals to abstract iodine atoms from alkyliodides.
The present invention discloses compounds of Formula (I), or pharmaceutically acceptable salts, esters, or prodrugs thereof:

A straightforward preparation of N-substituted cyclohex-3-enamines starting from the commercially available trans-4-aminocyclohexanol hydrochloride is described. Cyclohex-3-enamino-functionalized compounds have proven to be interesting intermediates in medicinal chemistry. The method here described is cheaper, more scalable and tolerant of a broader variety of functional groups than those found in
