Synthesis of Hyperolactones A and C

Hyperolactones A (1) and C (3) have been synthesized starting from (S)-malic acid by a straightforward route. The unique spirolactone skeleton was efficiently constructed by one-pot reaction as a key step. The absolute stereochemistry of hyperolactones was unambiguously established by this synthesis.
