Abstract: | Hydroxy sulfinyl dienes yielded functionalized tetrahydrofurans through nucleophilic and metal-catalyzed epoxidations.1] Fernández de la Pradilla, R., Manzano, P., Montero, C., Priego, J., Martínez-Ripoll, M. and Martínez-Cruz, L. A. 2003. J. Org. Chem., 68: 7755–7767. Google Scholar] Effective oxirane cleavage has been achieved in these systems and a formal synthesis of (?)-Kumausallene is reported. |
