摘要:
A diastereoselective, boron-mediated aldol process inspired by the natural product fostriecin is described. Using a tertiary alpha'-stereocenter as the induction element, aldol adducts are provided with high yields, good to excellent levels of diastereoselection, and broad substrate scope. An Evans-Tischencko reduction of the aldol adduct from cinnamaldehyde resulted in the C-8-C-11 stereotriad of ent-fostriecin. 2012 Elsevier Ltd. All rights reserved.
