propargyl ester followed by intramolecular [4+2] cycloaddition of vinylallene and unactivated alkyne was developed. This tandem reaction provides access to bicyclic compounds containing a highly functionalized isotoluene or cyclohexenone structural motif, while only aromatic compounds were observed in related transition metal-catalyzed cycloadditions.
开发了 Rh 催化的炔丙酯的 1,3-酰氧基迁移,然后是乙烯基丙二烯和未活化炔的分子内 [4+2] 环加成。这种串联反应提供了获得含有高度官能化异甲苯或环己烯酮结构基序的双环化合物的途径,而在相关的过渡金属催化的环加成反应中仅观察到芳香族化合物。
