The cyclization of the hydroxyacid (LV) by means of 2,4,6-trichlorobenzoyl chloride and TEA in THF/benzene gives the acetylenic macrolactone (LVI), which is reduced with Lindlar catalyst and 1-hexene in ethyl acetate to yield the cis-macrolactone (LVII). The Mom-protecting group of (LVII) is selectively removed by means of PPTS in tert-butanol to afford the allylic alcohol (LVIII), which is submitted to a Sharpless epoxidation with t-BuOOH, (+)-DET and Ti(OiPr)4 in dichloromethane providing the epoxide (LIX). Finally, the Pmb-protecting group of (LIX) is removed by means of DDQ in dichloromethane to furnish the target Laulimalide.
