report a unified synthetic strategy to access the protoilludane, mellolide, and marasmane families of naturalproducts. The key features of these syntheses are 1) the organocatalytic, enantioselective construction of key chiral intermediates from a simple achiral precursor, 2) the utility of a key 1,2‐cyclobutanediol intermediate to serve as a precursor to each naturalproduct class, and 3) a direct chemical
