Ley's group at the University of Cambridge carried out the first total synthesis of the bioactive alkaloid (+)-plicamine (Image 4) [Angew. Chem. Int. Ed., 41, 2194 (2002 ); C&EN, June 17, page 26 ]. All transformations used in the synthesis were done with supported reagents and scavengers, avoiding the need for any chromatographic, crystallization, or distillation steps.
