Synthesis of complex oxygenated heterocycles
Abstract:
Versatile and chemoselective preparation of substituted oxygenated heterocycles is described. Highly diastereoselective metal-catalyzed syntheses of trans-2,6- and cis-2,6-disubstituted tetrahydropyrans (THPs) are presented, along with an easy one-pot access to various ring size benzoannulated spiroketals.
