Manganese(III) acetate-mediated peroxycyclization between 2-hydroxy-3-methylnaphthoquinone and various alkenes was performed to obtain dihydronaphtho[2,3-c][1,2]dioxine-5,10(3H,10aH)-diones. The reactivity of symmetrical or unsymmetrical 1,1-disubstituted alkenes and monosubstituted alkenes allowed the synthesis of more than 50 original molecules. Focusing on the excellent reactivity of 2-hydroxy-
进行了乙酸锰(III)在2-羟基-3-甲基萘醌与各种烯烃之间的过氧环化反应,得到二氢萘[2,3- c ] [1,2]二恶英-5,10 (3H,10aH)-二酮。对称或不对称的1,1-二取代的烯烃和单取代的烯烃的反应性允许合成超过50个原始分子。着眼于2-羟基-3-甲基萘醌的出色反应性,我们描述了Mn(OAc)3的第一个例子与硝基取代的烯烃的反应性。讨论了合成产物的范围,局限性和立体化学。从单取代的烯烃开始,观察到一对非对映异构体的不稳定性,导致开环。
