required. Alkylation and conjugate addition reactions of trivalent phosphorus (P(III)) species were investigated. In situ generation of bis-trimethylsilyl esters of phosphinousacids proved to be an effective route to phosphinates of modest structural complexity. However, this chemistry could not be extended to the incorporation of an amino acid moiety at the N-terminal side of the desired phosphinate. A
