Abstract
A flexible and convergent strategy for the stereoselective total synthesis of bioactive marine natural product cytospolide Q has been developed. The key features of this synthesis include Evans anti-aldol reaction for the installation of C-2 and C-3 stereocenters and cycloetherification via epoxide opening followed by concomitant lactonization for the construction of tetrahydrofuran and γ-butyrolactone scaffolds. This synthetic study also revealed that protected oxygenated functionality (methyl ester or benzyl ether) at C-1 position participated readily in epoxide opening.
