A convergent stereoselectivetotalsynthesis of decarestrictineI (1) and botryolide B (1a) invoking a common synthetic strategy is reported. The key steps are: ring-closing metathesis of epoxy dienoic esters obtained through the Yamaguchi esterification of their respective intermediates to furnish the respective Z-macrocycles (2 and 2a) which were further extrapolated to their respective targets.

efficient total synthesis of botryolide B was achieved in 9 longest linear steps with 22% overall yield via esterification of a carboxylic acid with an alcohol fragment and a ringclosingmetathesis (RCM) reaction as pivotal steps to construct the macrolactonering system. Our novel approach for the synthesis of the 2-alkene-1,5-diol fragment was achieved by a ringclosingmetathesis reaction followed
