Teubrevin G and teubrevin H: The first total syntheses of rearranged neo-clerodanes including solutions to the problems of chirality merger and furan ring assembly

Total syntheses of teubrevins G (2) and H (3) are described. The reported strategy relies on a highly regioselective cycloaddition-fragmentation approach to the construction of a 2,3,4-trisubstituted furan and features efficient ring-closing metathesis ch
