Studies on the Origin of 1,5-anti Induction in Boron-Mediated Aldol Reactions

Stocker, Bridget L.,Teesdale-Spittle, Paul,Hoberg, John O.

, p. 330 - 336 (2004)

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. KGaA, 69451 Weinheim, Germany, 2004.
