摘要：

The direct carboxylation of benzoxasiloles with carbon dioxide proceeded smoothly under mild conditions using copper iodide as a catalyst to afford phthalides after an acid work-up. Broad substrate scope and application of this methodology for the synthesis of natural products highlight the synthetic utility of this protocol.
