New Cytotoxic Derivatives by the Phosphorylation and Phosphinoylation of Diethyl α‐Amino‐α‐Aryl‐Methylphosphonates

Chemistry – A European Journal, Volume 31, Issue 21, April 9, 2025.
In order to make available potentionally bioactive new α‐aminophosphonic derivatives, diethyl α‐amino‐α‐aryl‐methylphosphonates were phosphorylated, phosphinoylated and thiophosphinoylated with the corresponding P‐chloride. The effect of a P=O to P=S modification was evaluated by single crystal X‐ray cristallography.
