A practical and sustainable chemical process for the synthesis of highly substituted aldol↔lactol products was achieved for the first time through the asymmetric Barbas–List aldol (BLA) reaction of 2‐hydroxybenzaldehydes with acetone in the presence of a catalytic amount of trans ‐4‐OH‐ L ‐proline (see scheme).
