Abstract

We have employed computational methods to investigate the iridium-catalyzed allylic substitution leading to the formation of enantioenriched allyl carbamates from carbon dioxide (CO). The reaction occurs in several steps, with initial formation of an iridium-allyl, followed by nucleophilic attack by the carbamate formed in situ from CO and an amine. A detailed isomeric analysis shows that the rate-determining step differs for the ()- and ()-pathways. These insights are essential for understanding reactions involving enantioselective formation of allyl carbamates from CO.

摘要

我们采用了计算方法来研究铱催化的烯丙基取代反应,该反应可由二氧化碳(CO)生成对映体富集的烯丙基氨基甲酸酯。反应分几步进行,首先形成铱-烯丙基,随后原位由CO和胺形成的氨基甲酸酯进行亲核进攻。详细的异构体分析表明,()-和()-途径的速率决定步骤不同。这些见解对于理解涉及由CO对映选择性形成烯丙基氨基甲酸酯的反应至关重要。
