Reactive Dienes: Intramolecular Aromatic Oxidation of 3-(2-Hydroxyphenyl)-propionic Acids
摘要:
Treatment of 3-(2-hydroxyphenyl)-propionic acids with a hypervalent iodine reagent in the presence of a dienophile initiates a tandem intramolecular aromatic oxidation/Diels-Alder reaction. Herein we report (1) investigations on the scope and limitations of this novel reaction combination and (2) preliminary diastereoselectivity studies using alpha- and beta-substituted acids.
