摘要
A novel methodology for the synthesis of potential beta-secretase 1 (BACE-1) inhibitors has been elaborated from a beta-lactam precursor obtained by a Staudinger reaction. Ring opening of the beta-lactam gave access to a key intermediate trisubstituted tetrahydrofuran after a sequential reduction/Mitsunobu etherification. This strategy allowed a partial control of the stereochemistry through epimerization of the beta-lactam. Finally, the amidine was further modified by introducing an amide linker in order to deliver a putative BACE-1 inhibitor. (C) 2015 Elsevier Ltd. All rights reserved.
