We report a simple protocol for the synthesis of α-fluoro-β-aminophosphonates by the regioselective fluorination of α-hydroxy-β-aminophosphonates under mild conditions. The fluorination reactions were mediated by the PyFluor reagent and occurred with the retention of configuration. The main products of this reaction were a series of α-fluoro-β-aminophosphonates, which can be used as precursors in the preparation of medicinally important compounds (e.g., dipeptide analogues).
Copper-Catalyzed Regio- and Enantioselective Aminoboration of Unactivated Terminal Alkenes

Interest in synthesis of fluorinated aminophosphonates has grown significantly in recent years due to their promising applications in medicinal and bioorganic chemistry. We report herein efficient and general methods for the synthesis of α- and β-monofluo
Preparation of aminoalkyl chlorohydrin hydrochlorides: Key building blocks for hydroxyethylamine-based HIV protease inhibitors
Beaulieu, Pierre L.,Wernic, Dominik
, p. 3635 - 3645 (2007/10/03)
Enantiomerically pure N,N-dibenzyl-α-amino aldehydes reacted with (chloromethyl)lithium, generated in situ from bromochloromethane and lithium metal, to give predominantly erythro aminoalkyl epoxides. Treatment of the crude epoxides with aqueous hydrochloric acid gave crystalline (2S,3S)-N,N-dibenzylamino chlorohydrin hydrochlorides in 32-56% overall yield and high isomeric purity. These compounds are versatile synthetic intermediates for the preparation of hydroxyethylamine-based HIV protease inhibitors, either directly as such, or via conversion to the corresponding N-Boc(2S,3S)-aminoalkyl epoxides. The processes described do not make use of hazardous reagents or intermediates, do not require chromatographic purifications, and are thus amenable to the preparation of large quantities of these versatile building blocks.
