highly enantioselectivebromolactonizations of a number of structurally distinct unsaturated acids. Like some known catalysts, this catalyst promotes highly enantioselectivebromolactonizations of 4- and 5-aryl-4-pentenoic acids, but it also catalyzes the highly enantioselectivebromolactonizations of 5-alkyl-4(Z)-pentenoic acids. These reactions represent the first catalytic bromolactonizations of alkyl-substituted
