Resumen: Bryostatin 1 34, produced by a bacterial symbiont of the marine bryozoan Begula neritina, has shown promise for the treatment of Alzheimer’s disease. This work reports the divergent total syntheses of bryostatins, obtaining 1.5 g of bryostatin 1 in the final three steps. Key methods include Ni-catalyzed reductive cross-coupling, flow-assisted light-induced radical addition, and a Prins cyclization for cis-Z selectivity. The syntheses require 20–22 linear steps (33–35 total) with overall yields of 3.3–4.5%.
