  1,4-Induction in aldol reactions of (tertiary α′-alkoxy)methyl ketones: synthesis of the C8–C11 stereotriad of ent-fostriecin

  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.
