First Total Syntheses and Spectral Data Corrections of 11-α-Methoxycurvularin and 11-β-Methoxycurvularin

摘要

Concise and efficient total syntheses of 11-α-methoxycur-vularin and 1 l-β-methoxycurvularin were accomplished for the first time. The three-component linchpin coupling and intramolecular acylation reactions were key steps, in which we found the spectral data of 11-α-methoxycurvularin and ll-β-methoxycurvularin, reported in the literature, were reversed with each other.
