Palladium-Catalyzed Regioselective [3+2] Cycloadditions of α,β-Unsaturated Imines with Vinylethylene Carbonates: Access to Oxazolidines

Catalysts, Journal Year: 2024, Volume and Issue: 14(8), P. 508 - 508

Published: Aug. 6, 2024

We reported palladium-catalyzed regioselective [3+2] cycloadditions of α,β-unsaturated imines with vinylethylene carbonates, providing the desired oxazolidines in moderate-to-high yields. This reaction provides a facile route for highly synthesis functional oxazolidines. The synthetic utility current method was also demonstrated by gram-scale reaction.
