Abstract The trans-epoxide derivative of Combretastatin A-4 wasstereoselectively prepared in good yield by sulfur ylide mediated epoxidation of silyl-protected isovanillin. From this key intermediate, a formal synthesis of CA-4, by stereoselective deoxygenation and photoisomerization, was achieved. Alternatively, a trans-dioxolane derivative was obtained bystereoselective acetone insertion.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 ...
