2 (see SI). The OH group at the quinine is presumably converted into O-Se-Ph (for an example in the reaction of PhSeCl with alcohols, see:;), whereas the thiourea evolves into a very complex mixture of species. It would explain the absence of catalytic activity and the formation of the racemic mixtures. Moreover, we have checked that this reaction occured in the absence of catalyst
