title: Total syntheses of clausamines A-C and clausevatine D.
abstract: The first total syntheses of clausamines A-C and clausevatine D are reported. The key step involves a Diels-Alder reaction between an imine quinone and cyclic diene, allowing for the subsequent construction of the carbazole core in a regiospecific manner. Stereochemistry of the natural products is also discussed.
