title: Asymmetric total synthesis of martinelline and martinellic acid.
abstract: Herein, we describe the first asymmetric total synthesis of (-)-martinelline ((-)-2) and the second total synthesis of (-)-martinellic acid ((-)-1) by employing a tandem Mukaiyama-Mannich reaction/aminal cyclization as the key step.
