DAST mediated preparation of β-fluoro-α-aminophosphonates
摘要:
Herein, we report a new and convenient method for the synthesis of beta-fluoro-alpha-aminophosphonates starting from naturally occurring L-amino acids. A key step in the synthetic protocol involves nucleophilic fluorination of N,N-dibenzylated-beta-amino alcohols with diethylaminosulfur trifluoride (DAST). (C) 2012 Elsevier B.V. All rights reserved.
