We have accomplished the synthesis of ‘hypotheticalmacroketone’ (a novel migrastatin analogue) for the first time. We have used TiCl4 mediated vinylogous Mukaiyama aldol reaction (VMAR) to establish the required three stereocenters on the key intermediate. Grubbs’ 2nd generation catalyzed RCM reaction was utilized to construct the 14 membered ring macrocycle.
The present invention provides compounds having formula (I): (I) wherein n, R

The first totalsynthesis of (+)-migrastatin, a macrolide natural product with interesting antimetastatic properties, has been accomplished. Our concise and flexible approach utilizes a Lewis acid-catalyzed diene aldehyde condensation to install the three contiguous stereocenters and the trisubstituted (Z)-alkene of migrastatin. Construction of the two remaining stereocenters and incorporation of the

A significantly simpler analog of the natural product migrastatin, termed migrastatin ether (ME), has been prepared and evaluated. Both in vivo and in vitro studies indicate that ME exhibits a concentration-dependent inhibitory effect on migration of breast cancer cells.
