aminocatalysis (see scheme) allows them to undergo [4+2] cycloadditions with concomitant breaking of the aromaticity at room temperature and low catalyst loadings. A highly enantioselective Diels–Alder reaction of anthracenes has been developed using nitroalkenes as dienophiles.

蒽通过
氨基催化的活化(参见方案)使它们能够进行[4 + 2]环加成反应,并在室温和低催化剂负荷下伴随着芳香性的破坏。使用硝基烯烃作为亲二烯体,已经开发出
蒽的高度对映选择性Diels-Alder反应。
