The first total synthesis of brasilicardins A and C, novel diterpenoid-saccharide-amino acid hybrid metabolites with unique immunosuppressive activity, is described. The key step is a Diels-Alder/reductive angular methylation sequence capitalizing on a trans-fused bicyclic α-cyano-α,β-enone as its precursor to construct the 8,10-dimethyl-trans/syn/trans-perhydrophenanthrene skeleton. Other notable features include an anti-selective aldol reaction, a stereocontrolled glycosylation of a C2 alcohol, and a one-pot, two-step global deprotection sequence that did not damage these sensitive molecules.
