We found that chemoselectivity of the crossed acyloin product is controlled by the adjustment of the aromatic aldehyde/aliphatic aldehyde ratio. Moreover, we observed the persistent catalytic activity of the homogeneous NHC catalyst in a solution due to NHC catalyst robustness.
Construction of benzofuranone library <i>via</i> a metal-free, one-pot intermolecular condensation, and their application as efficient estrogen receptor β modulators
Facilesynthesis of benzofuranone was achieved through a metal-free, one-pot intermolecular condensation between α-hydroxy aryl ketones and resorcinol derivatives. A library of 20 compounds with moderate to good overall yields was prepared. These compounds showed strong binding toward estrogen receptors along with good selectivity for ERβ (>190-fold over ERα).
