Total synthesis and structural confirmation of (±)-spirocollequins A and B
Keita Ichikawa, Toshiyasu Inuzuka, Hidemi Yoda and Tetsuya Sengoku
Tetrahedron Letters 2022, 107, 154109. (DOI: 10.1016/j.tetlet.2022.154109)
The first total synthesis of antiplasmodial isoindolinone alkaloids, spirocollequins A and B, has been accomplished. The proposed structures of spirocollequins have been supported through the comparison of spectroscopic properties of the synthetic samples with those of natural products as well as single-crystal X-ray diffraction analysis using a synthetic precursor of spirocollequin B.
