A model for the origin of selectivity in boron-mediated 1,5-anti-aldols is presented. This model involves π-stacking between the boron enolate and a remote aromatic ring. A short, facile method for the synthesis of the C-12 to C-22 segment of peloruside A and its 1,5-anti-aldol coupling using the proposed model is also presented. (© Wiley-VCH Verlag GmbH & Co.
