  摘要：

  AbstractVisible light‐mediated decarboxylation using N‐acyloxyphthalimides as the source for carbon‐centered radicals was applied for the synthesis of spirobutenolides. The utility of this approach is demonstrated with the formal synthesis of (S)‐(+)‐lycoperdic acid. Alternatively, 2,3‐anellated furans can be obtained in a one‐pot procedure via photocyclization following a regioselective semipinacol rearrangement.magnified image
