compounds in carbon dioxide (CO2) atmosphere under mild conditions. It was found that CO2 could be incorporated at the diketone enolic OH position, which was key to enabling the cleavage of a C–O bond during the rearrangement of a cyclopropane intermediate. This method allows for the same-pot construction of two isomers of the high-value tetra-substituted furan scaffold. The synthetic scope and preliminary
我们报告了一个简单的协议,用于在温和条件下在二氧化碳 (CO 2 ) 气氛中将 1,3-二酮转化为无过渡金属、可见光驱动的四取代呋喃骨架化合物。发现CO 2可以掺入二酮烯醇OH位置,这是在环丙烷中间体重排期间能够裂解C-O键的关键。该方法允许高价值四取代呋喃支架的两种异构体的同一罐构造。介绍了合成范围和初步机理研究。
