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.

Reaction of arylacetic acid enolates with 2-tosyloxyalkanes gave with high anti-selectivity 2-aryl-3-methylalkanoic acids which were useful synthetic intermediates of ferroelectric liquid crystals.
