Gold(I)-Catalyzed Amination of Allylic Alcohols with Cyclic Ureas and Related Nucleophiles
摘要:
A 1:1 mixture of [P(t-Bu)(2)-o-biphenyl]AuCl and AgSbF6 catalyzes the Intermolecular amination of allylic alcohols with 1-methylimidazolidin-2-one and related nucleophiles that, in the case of gamma-unsubstituted or gamma-methyl-substituted allylic alcohols, occurs with high gamma-regloselectivity and syn-stereoselectivity.

enables selective incorporation of alkenyl, alkynyl and allyl functional groups into the C(sp3)–H bond under green reaction conditions is developed. The process is based on the catalytic formation of α-alkoxyl/α-amidyl radicals via the homolytic activation of the C(sp3)–H bond of ethers/amides with a catalytic amount of diarylketone in the presence of a household fluorescent light bulb. This simple reaction
