Fluorinated Para ‐Quinone Monoacetal: Versatile Reactivity for Constructing Functionalized Scaffolds

ABSTRACT A concise synthetic route to the difluorinated para ‐quinone monoacetals ( p ‐QMAs) and their reactivity is described. Featuring a cross‐conjugated dienone core and an acetal unit, these compounds undergo diverse nucleophilic additions at the enone moiety and cycloadditions at the C═C bond. Such distinctive reactivity renders the β,β′‐difluoro p ‐QMA a versatile building block for the rapid assembly of complex molecular architectures, highlighting its promise in natural product synthesis and material sciences.
