Palladium-Catalyzed [5 + 4] Cycloaddition of 4-Vinyl-4-Butyrolactones with N-Tosyl Azadienes: Construction of Nine-Membered Ring

The Journal of Organic Chemistry
In this paper, we reported the palladium-catalyzed formal [5 + 4] cycloaddition reactions between 4-vinyl-4-butyrolactones (VBLs) and azadienes. Under mild reaction conditions, a wide range of benzofuran-fused 9-membered heterocyclic compounds had been provided in moderate to excellent yields with exclusive regioselectivities and excellent ...

Palladium-catalyzed [3 + 2] cycloaddition of 4-vinyl-4-butyrolactones with sulfamate-derived cyclic imines: construction of sulfamate-fused pyrrolidines

Organic & Biomolecular Chemistry
The palladium-catalyzed [3 + 2] decarboxylative cycloaddition of 4-vinyl-4-butyrolactones with sulfamate-derived cyclic imines has been developed, providing the sulfamate-fused pyrrolidine derivatives in high yields with good diastereoselectivities.

Palladium-Catalyzed [3 + 2] Cycloaddition of 4-Vinyl-4-butyrolactones with Ketenes Generated in Situ from Acyl Chlorides: A Method for the Synthesis of Dihydrofurans

Organic Letters
In this paper, palladium-catalyzed [3 + 2] cycloaddition of 4-vinyl-4-butyrolactones with ketenes generated from easily available acyl chlorides was achieved. With Pd2(dba)3·CHCl3/XantPhos as the catalyst, the reaction proceeded smoothly under mild reaction conditions, affording a series of 2,3-dihydrofurans in moderate to high yields.
