碳阳离子级联反应导致的三环倍半萜并环戊二烯的机制建议进行评估的同位素敏感的分支实验与H309 A突变体的并环戊二烯合酶的结果。这些实验结果支持并环戊二烯形成的机制,涉及7-protoilludyl阳离子中间体,这是第一次使用量子化学计算预测。
Mechanistic proposals for the carbocation cas cade reaction leading to the tricyclic sesquiterpene pentalenene are assessed in light of the results of isotopically sensitive branching experiments with the H309A mutant of pentalenene synthase. These experimental results support a mechanism for pentalenene formation involving a 7-protoilludyl cation intermediate that was first predicted using quantum chemical calculations.
