Sterically congested compounds, such as 6,7-di-t-butyl-1,4-naphthoquinone, 2,3,6,7-tetra-t-butylanthraquinone, and 2,3,6,7-tetra-t-butylanthracene, were synthesized via a Diels–Alder reaction involving 3,4-di-t-butylthiophene 1-oxide as the key step.
通过以 3,4- 二叔丁基噻吩 1-氧化物为关键步骤的 Diels-Alder 反应,合成了 6,7- 二叔丁基-1,4-萘醌、2,3,6,7-四叔丁基蒽醌和 2,3,6,7- 四叔丁基蒽等立体拥塞化合物。
