Abstract:
A strategy featuring ring-closing metathesis as key reaction is applied to the synthesis of the sarcodictyin analogue 15. The precursor diene is accessed via a brief and efficient protocol, employing multiple stereoselective allylations. Simplified analogue 15 retains microtubule stabilising properties.
