Provided herein is a compound of Formula I, or a salt thereof, ##STR00001##
wherein R.sup.1 is a moiety having the following structure: ##STR00002##
wherein Z is selected from the group consisting of O and N; X is selected from the group consisting of a bond, NH, and C(O)NH; and A is selected from the group consisting of substituted aryl and substituted heteroaryl. Compounds of Formula I are useful as opioid receptor agonists. Because the compounds exhibit relatively low levels of -arrestin recruitment, they do not produce the negative side effects commonly associated with morphine-derived compounds.

Described herein is the development of an arenophile-mediated, nickel-catalyzed dearomative trans-1,2-carboamination protocol. A range of readily available aromatic compounds was converted to the corresponding dienes using Grignard reagents as nucleophiles. This strategy provided products with exclusive trans-selectivity and high enantioselectivity was observed in case of benzene and naphthalene. The utility of this methodology was showcased by controlled and stereoselective preparation of small, functionalized molecules. A concise synthesis of (+)-pancratistatin and (+)-7-deoxypancratistatin from benzene using an enantioselective, dearomative carboamination strategy has been achieved. This approach, in combination with the judicious choice of subsequent olefin-type difunctionalization reactions, permits rapid and controlled access to a hexasubstituted core. Finally, minimal use of intermediary steps as well as direct, late stage C-7 hydroxylation provides both natural products in six and seven operations.
