摘要

The quinoid nucleus embodies the potential of being a highly useful structural building block in organic synthesis. To date, the applications of quinones in complex natural products synthesis have centered around the Diels-Alder reaction.'The major problems associated with executing carbon-carbon bond forming reactions on either quinones or hydroquinones lie with the generally high reactivity of these species with nucleophiles and electrophiles, ...
