Enantioselective syntheses of the assigned structures of the helibisabonols A and B

The enantioselective syntheses of the compounds with the assigned structures of the helibisabonols A and B have been accomplished. Using an enzymatic desymmetrization of the σ-symmetrical diol (route a) and a diastereoselective conjugate addition of the m

Enantioselective syntheses of heliannuols G and H

Enantioselective total syntheses of the proposed structures for heliannuols G and H have been accomplished. However, their spectral properties were not identical with those of the natural products.
