Starting from 2-alkylidene-3-methylsuccinimides, simple and efficient synthesis of the natural products striatisporolide A, lichesterinic acid and lichesterylic acid have been demonstrated via an acid catalyzed hydrolysis, esterification, OsO4- dihydroxylation and dehydrative cyclization pathway.

The vicinal dianion 2 derived from triethyl ethanetricarboxylate reacted regioselectively with aldehydes and ketones at C(β) to provide paraconic acid derivatives 5a-f in moderate to high yields as mixtures of diastereoisomers. The paraconic acid derivatives 5e and 5f were utilized as the starting materials for the syntheses of (±)-lichesterinic acid (12), (±)-phaseolinic acid (13), (±)-nephromopsinic acid (14), (±)-rocellaric acid (15), and (±)-dihydroprotolichesterinic acid (16).
