title: Concise total syntheses of (±)-noruleine and (±)-uleine.
abstract: The first total synthesis of (±)-noruleine and a concise synthesis of (±)-uleine have been accomplished via the DDQ mediated dehydrogenative cyclization of a tetrahydrocarbazole derivative bearing a non-substituted amide functionality to prepare the key azocino[4,3-b]indole precursor.
