Catalytic Synthesis of 2H-Chromenes
TL;DR: This review gives an up-to-date overview of different catalytic methodologies developed for the synthesis of 2H-chromenes and is structured around the three main approaches applied in catalytic 2h-chromene synthesis: catalysis with (transition) metals, metal-free Bronsted and Lewis acid/base catalysis, and enantioselective organo-catalysis.
