A new series of phosphonylated triazolo[4,5-b]pyridine (1-deaza-8-azapurine), imidazo[4,5-b]pyridine (1-deazapurine) and imidazo[4,5-b]pyridin-2(3H)-one (1-deazapurin-8-one) were synthesized from 2-chloro-3-nitropyridine and selected diethyl ?-aminoalkylp

Herein, we report a new and convenient method for the synthesis of β-fluoro-α-aminophosphonates starting from naturally occurring l-amino acids. A key step in the synthetic protocol involves nucleophilic fluorination of N,N-dibenzylated-β-amino alcohols with diethylaminosulfur trifluoride (DAST).
