Bifunctional tertiary amine thio

The extension of the thiourea-tertiary amine concept to the cinchona alkaloids was reported by several groups independently in 2005. The general usefulness of cinchona alkaloids as bifunctional catalysts was recognized by several groups even before this date [9]. The focus herein is on (thio)urea and squaramide catalysts since they are prototypes of more efficient catalysts. The Chen and the Dixon groups screened cinchonine and cinchonidine-derived thiourea catalysts for conjugate... [Pg.187]
