Abstract
A convenient preparation of 3,4-bis methylenecyclopentanone ethylene ketal, a new valuable diene for Diels-Alder reaction, designed to produce functonalized [6,5]ring systems, is described. A formal synthesis of Gibberellic acid GA3 demonstrates the value of this methdology.File in questo prodotto:
