Fluorinated <i>Para</i> ‐Quinone Monoacetal: Versatile Reactivity for Constructing Functionalized Scaffolds

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.
