Model studies on construction of the oxabicyclic [3.3.1] core of the mulberry Diels–Alder adducts morusalbanol A and 441772-64-1
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...

| 总结: | 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 a dehydroprenyl diene. Results from these studies provide important insights into the syntheses of morusalbanol A and related mulberry Diels–Alder adducts. |
