Preparation of the oxabicyclic [3.3.1] cores of morusalbanol A and 441772-64-1 was achieved via the intramolecular cyclization of cis–trans (endo) mulberry Diels–Alder adducts. The latter were derived from a hydrogen bond-assisted regioselective Diels–Alder reaction between a chalcone dienophile and...
