Synthesis of carbohydrate containing crownethers tuned with steric and micro-environmental features and their application as catalysts in the Michael addition of methyl phenylacetate to methyl acrylate to give a chiral product is reported. The mechanistic rationale of the asymmetric induction is discussed.
