Catalytic Domino Annulations through η3‐Allylpalladium Chemistry: a Never‐Ending Story

Annulative \eta3-allylpalladium chemistry has been a longstanding trending research topic since the 80's. Nowadays, this research area is still providing challenges to the catalysis community leading to the development original and brand-new transformations. Several reaction partners have been used as precursors for \eta3-allylpalladium species, namely allyl diacetates, allyl monoacetates, 3-acetoxy-2-trimethylsilylmethyl-1-propene (ASMP), alkylidene cyclopropanes (ACPs), vinyl cyclopropanes (VCPs), vinyl aziridines, and vinyl epoxides. This minireview is intended to show the recent developments in the field of annulative \eta3-allylpalladium chemistry with emphasis on new reactivity, enantioselective transformations as well as potential applications in total synthesis.
