LITERATURE
37
-
increasing the reaction temperature to 37°C decreases the fidelity of Cop4. At 37°C Cop4 generates a relative larger fraction of products beta-cubebene, sativene, delta-cadinene and beta-copaene that are derived from a cadinyl cation intermediate
4 - 25
-
lowering the reaction temperature from 25°C to 4°C increases the selectivity of Cop4 for (?)-germacrene D and decreases the fraction of structurally unidentified sesquiterpene olefins by half
