“…The synthesis of α-substituted phosphoryl derivatives (phosphonic and phosphinic acids) has attracted significant attention because of their biological activities, with broad application as enzyme inhibitors, antimetabolites, and antibiotics [15]. Among α-functionalized phosphonic acids, (aminomethyl)phosphonic acids have biological activities such as antibacterial, herbicidal, and fungicidal [16][17][18]. (Aminomethyl)phosphonic acids, the phosphonic acid analogues of 1-amino carboxylic acids, are an important class of compounds that exhibit a variety of interesting and useful properties.…”
