Fujiyoshi, Kohei;Kawashima, Shigehiro A.;Yamatsugu, Kenzo;Kanai, Motomu research published 《 A Single-Step Asymmetric Phosphodiester Synthesis from Alcohols with Phosphoenolpyruvate Phosphodiester》, the research content is summarized as follows. Phosphodiesters ROP(O)(OH)(OR¹) (12–31; R = 3-arylpropyl, phenethyl, carbohydrate, steroid, amino acid; R¹ = Me, Et) were prepared by organocatalytic transesterification of phosphoenolpyruvate (R¹O)₂P(O)OC(:CH₂)CO₂H in the presence of 1 equiv of Me nicotinate.

Fung, Alfred. K. K.;Yu, Li-Juan;Sherburn, Michael S.;Coote, Michelle L. research published 《 Atom Transfer Radical Polymerization-Inspired Room Temperature (sp³)C-N Coupling》, the research content is summarized as follows. A simple nonphotochem. procedure is reported for Cu(I)-catalyzed C-N coupling of aliphatic halides with amines and amides. The process is loosely based on the Goldberg reaction but takes place readily at room temperature It uses Cu(I)Br, a commonly used and inexpensive atom transfer radical polymerization precatalyst, along with the cheap ligand N,N,N’,N”,N”-pentamethyldiethylenetriamine, to activate the R-X bond of the substrate via inner-sphere electron transfer. The procedure brings about productive C-N bond formation between a range of alkyl halide substrates with heterocyclic aromatic amines and amides. The mechanism of the coupling step, which was elucidated through application of computational methods, proceeds via a unique Cu(I) → Cu(II) → Cu(III) → Cu(I) catalytic cycle, involving (a) inner-sphere electron transfer from Cu(I) to the alkyl halide to generate the alkyl radical; (b) successive coordination of the N-nucleophile and the radical to Cu(II); and finally reductive elimination. In the absence of a nucleophile, debrominative homocoupling of the alkyl halide occurs. Control experiments rule out SN-type mechanisms for C-N bond formation.
