Abstract

Formal Asymmetric Synthesis of Pentalenolactone E and Pentalenolactone F. Part 2. Construction of the Angular Diquinanoid δ-Lactone.-An asymmetric synthesis of the diquinanoid δ-lactone (XI), a known precursor of pentalenolactones E and F, starts from (I). The latter was prepared in the preceding paper.-(HERRMANN, E.; GAIS, H.-J.; ROSENSTOCK, B.; RAABE, G.; LINDNER, H. J.; Eur.
