A Gram-Scale Batch and Flow Total Synthesis of Perhydrohistrionicotoxin

Biologically valuable histrionicotoxin spiropiperidine alkaloids are found in the Colombian poison arrow frog Dendrobates histrionicus (shown on the cover). In their Full Paper on page 11471 ff., J. H. Ryan et al. describe efforts to synthesize an unnatural analogue, perhydrohistrionicotoxin, by combining conventional with microreactor techniques.
