First Total Syntheses and Spectral Data Corrections of 11-α-Methoxycurvularin and 11-β-Methoxycurvularin
摘要:
[Graphics]Concise and efficient total syntheses of 11-alpha-methoxycurvularin and 11-beta-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-alpha-methoxycurvularin and 11-beta-methoxycurvularin, reported in the literature, were reversed with each other.

Stereoselective syntheses of 11-α-methoxycurvularin and 11-β-methoxycurvularin
A stereoselective synthesis of potent cytotoxic macrolides, 11-alpha-methoxycurvularin and 11-beta-methoxycurvularin has been accomplished. The synthesis entailed Maruoka asymmetric allylation to introduce the stereocentres at C-11 and the key fragment was installed by using Grubbs cross-metathesis followed by CBS-reduction.
