Azizollahi, Hamid; Mehta, Vaibhav P.; Garcia-Lopez, Jose-Antonio published the artcile< Pd-catalyzed cascade reactions involving skipped dienes: from double carbopalladation to remote C-C cleavage>, Category: bromides-buliding-blocks, the main research area is spirocycle preparation; diene double carbopalladation cascade palladium catalyst; allyl benzofuran preparation; skipped diene beta elimination palladium catalyst.
Herein, two ligand-controlled cascade reactions relying on the intramol. carbopalladation of skipped dienes were reported. The use of a bulky monodentate phosphine ligand afforded [4,5]-spirocycles I [R = H, 5-Me, 6-F, etc.] via sequential double carbopalladation, however bidentate phosphines promoted Pd-catalyzed remote β-C-elimination cascade to afford 3-allyl-substituted benzofurans II.
