    Abstract: The [3333]-2-one conformation is the preferred conformation of cyclododecanone and carbonyl is vertical to the near ring plane. To explore the stereochemistry of substituted cyclododecanone is beneficial to understanding their stability, reactivity and structure-activity relationships of these compounds. The cis- and trans- isomerism of the macrocy... Show More
