A desymmetrization protocol has been used to develop a palladium catalyzed enantioselective carbonylation process. Achiral cyclic bis-alkenyltriflates are converted to their corresponding monoester derivatives with selectivities of up to 96% ee.
脱对称方案已用于开发钯催化的对映选择性羰基化过程。非手性环状双烯基三氟甲磺酸酯转化为其相应的单酯 选择性高达96%ee的衍生物。
