The first and collective total syntheses of periconiasins A–E, a group of naturally occurring cytochalasans, were achieved by a series of rationally designed or bioinspired transformations. Salient features of the syntheses include a tandem aldol condensation/Grob fragmentation to assemble the linear polyketide–amino acid hybrid precursor, a Diels–Alder macrocylization to construct the 9/6/5 tricyclic core of periconiasins A–C, and a transannular carbonyl–ene reaction to forge the polycyclic framework of periconiasins D and E.
