Novel Applications of Raney Nickel/Isopropanol: Efficient System for the Reduction of Organic Compounds

Deoxyfluorinating reagents as tools for γ-amino-α-hydroxyphosphonate modification

Herein, we would like to present deoxyfluorinating reagents such as DAST and PyFluor and their successful use as tools for selective modification of γ-amino-α-hydroxyphosphonates. Depending on the deoxyfluorinating reagent applied, an intramolecular cyclization leading to phosphonates containing the 1,3-oxazinan-2-one moiety or direct nucleophilic deoxyfluorination yielding the α-fluorinated derivatives of γ-aminophosphonates was observed. The obtained compounds may be used as precursors in the preparation of medicinally important compounds e.g., dipeptide analogues or scaffolds containing the 1,3-oxazinan-2-one group.

Efficient access to chiral 1,2-amino alcohols via Ir/f-amphox-catalyzed asymmetric hydrogenation of α-amino ketones

We successfully developed the iridium/f-amphox-catalyzed asymmetric hydrogenation of α-amino ketones to prepare chiral 1,2-amino alcohols with excellent results.
