## Abstract A series of chiral, __C__~2~ symmetric tridentate __N__‐heterocyclic carbene precursors, containing two __N__‐functionalized hydroxyl or alkoxyl groups, were synthesized. They were applied to catalyze the asymmetric conjugate addition of diethylzinc to cyclohex‐2‐enone and cyclopent‐2‐e

✦ Synopsis
Abstract
If cyclopent‐2‐enone (IV) instead of cyclohex‐2‐enone (I) is used for the title reaction, the stereochemistry is reversed and the enantioselectivity is much lower.
