Gassman’s Intramolecular [2 + 2] Cationic Cycloaddition. Formal Total Syntheses of Raikovenal and epi-Raikovenal
摘要:
The first intramolecular version of Gassman's cationic [2 + 2] cycloaddition employing vinyl acetals tethered to an unactivated olefin and its application in the formal syntheses of raikovenal and epi-raikovenal are described.
