Abstract: A novel, recyclable, thiourea‐based asymmetric organocatalyst containing a hydrophobic anchor has been developed. The chemical nature of the hydrophobic anchor contributes to the desirable characteristics of the recyclable catalyst. The hydrophobic anchor‐tagged thiourea catalyst is… read more here.

Abstract: A novel spiro-pyrrolidine (SPD)-derived bifunctional thiourea catalyst has been developed, enabling the development of a stereoselective conjugate addition of furfurals to β,γ-unsaturated α-ketoesters. The reaction represents an example of asymmetric trienamine catalysis in the benzylic… read more here.
