✦ Synopsis

The synthesis of syn-2,4-dimethyl-l-tetralone 6 via a deprotonation-reprotonation strategy using chelating proton sources is discussed. We comment on the differences between direct protonation and deprotonation-reprotonation ofchiral enolates in the presence of diisopropylamine and LiBr.
