An enantioselective route to the title compound, a heteroatom Substituted close analogue of natural brefeldin A, is described. As a key step in the whole synthesis, concatenation of the lower chain and the cyclopentanone-Upper chain moiety was achieved using a Rh-catalyzed Michael addition of a vinyl boronic acid to an enone, which effectively eliminated the problems encountered with the corresponding cuprate protocol and exemplified the potential of the strategy in synthesizing similar analogues.
