A simple and efficient protocol for silver-promoted direct C–H phosphonation of 1-naphthylamine derivatives with H-phosphonates was described. This reaction proceeded smoothly for 1-naphthylamine derivatives at the C4 site, providing a facile and efficient route to 4-phosphonated 1-naphthylamine derivatives. This phosphonation could tolerate a diverse type of functional groups at the pyridinyl and

A highly efficient [1,2]-Brook rearrangement of silyl glyoxylates has been developed using DBU as the organobase-catalyst. This [1,2]-Brook rearrangement is applicable to a number of thiols and secondary phosphine oxides containing acidic protons. These nucleophiles afford the corresponding Brook products in high yields. Using this methodology, a formal synthesis of anti-HIV drug compound lamivudine

A cascade radicalcyclization was realized for the first silver-promoted imino-phosphorylation of γ,δ-unsaturated oxime esters, which provided a step-economical and redox-neutral route to access a variety of phosphorylated pyrrolines in good to excellent yields. Moreover, a new bulky trivalent phosphine ligand with a pyrroline motif was obtained through a deoxidation process.
