[摘要]：Oxabenzonorbornadienes are valuable synthetic intermediates because they can serve as a general template with which to create highly substituted ring systems. However, to date, only very few C1-substituted oxabenzonorbornadienes have been reported. In this study, the synthesis of some C1-substituted oxabenzonorbornadienes was achieved by the Diels-Alder reaction between 2-substituted furans and benzyne. Moderate to good yields (16-80%) of the Diels-Alder reactions were observed. These C1-substituted oxabenzonorbornadienes will find applications as valuable synthetic intermediates and should be useful in studies of transition-metal-catalyzed reactions. |
