Abstract

(Chemical Equation Presented) Readily available cinchona alkaloids have been used as organocatalysts in the highly efficient stereoselective hydroxyalkylation of heteroaromatics such as indoles with 3,3,3- trifluoropyruvate (2, see scheme). High yields and ee values of both enantiomers of the products, depending on the catalyst used, indicate the usefulness of the developed methodology.
