1-Methoxy-3-trimethylsiloxy-1, 3-butadiene (Danishefsky's diene) is recognized as a synthetically useful diene due to its high reactivity in the Diels− Alder reaction with electron- deficient alkenes to give oxygen-functionalyzed cyclohexenes and substituted cyclohexenones, which are important building blocks for the total synthesis of natural products. However, the development of catalytic enantioselective versions of Diels− Alder ...
