Optimization of Phosphoramidates Synthetic Conditions

An optimized catalytic oxidative cost effective process of dehydrogenative coupling of diisopropyl phosphite with arylamines led to formation of the corresponding phosphoramidates. Structures of products were elucidated from NMR and ESI-MS data.

Redox-Neutral P(O)-N Coupling between P(O)-H Compounds and Azides via Dual Copper and Photoredox Catalysis

We report a redox-neutral P(O)-N coupling reaction of P(O)-H compounds with azides via photoredox and copper catalysis, providing new access to useful phosphinamides, phosphonamides, and phosphoramides. This transformation tolerates a wide range of nucleophilic functionalities including alcohol and amine nucleophiles, which makes up for the deficiency of classical nitrogen nucleophilic substitution reactions. As a demonstration of the broad potential applications of this new methodology, late-stage functionalization of a diverse array of azido-bearing natural products and drug molecules, a preliminary asymmetric reaction, and a continuous visible-light photoflow process have been developed.

Trichloroisocyanuric Acid as an Efficient Reagent for the Synthesis of Phosphoroamidates via Atherton-Todd Reaction under Base-Free Conditions

A simple, efficient, and novel method is developed for the synthesis of phosphoroamidates via an Atherton-Todd coupling reaction of amines with dialkyl H-phosphite using trichloroisocyanuric acid as an efficient and safe reagent. Treatment of amines with dialkyl H-phosphite and trichloroisocyanuric acid under base-free conditions gives phosphoroamidates in moderate to good yields. The reaction proceeded effectively to afford the corresponding phosphoroamidates via a dehydrogenative coupling of H-phosphonates with amines. This method is easy, rapid, and good-yielding for the synthesis of phosphoroamidates.

Fe3O4@MgO nanoparticles as an efficient recyclable catalyst for the synthesis of phosphoroamidates via the Atherton-Todd reaction Dedicated to Professor Tsutomu Yokomatsu from Tokyo University of Pharmacy and Life Sciences on the occasion of his 65th birthday

A simple and efficient method is presented for the synthesis of phosphoroamidates in moderate to good yield via the Atherton-Todd coupling of primary amines with H-dialkyl phosphites using Fe3O4@MgO nanoparticles as a recyclable catalyst.

Copper-catalyzed aerobic oxidative cross-coupling of arylamines and dialkylphosphites leading to N-arylphosphoramidates

An efficient method to generate N-P bonds directly from N-H and P-H bonds is described. Various arylamines and dialkylphosphites were directly oxidized to the corresponding N-arylphosphoramidates at room temperature in moderate to good yields by using an inexpensive catalyst-oxidant (CuBr/air) system.

Kinetics and mechanism of the anilinolysis of diisopropyl chlorophosphate in acetonitrile

The nucleophilic substitution reactions of diisopropyl chlorophosphate (3) with substituted anilines (XC6H4NH2) and deuterated anilines (XC6H4ND2) are investigated kinetically in acetonitrile at 55.0 oC. The anilinolysis rate of 3 is rather slow to be rationalized by the conventional stereoelectronic effects. The obtained deuterium kinetic isotope effects (DKIEs; kH/kD) are secondary inverse (kH/kD = 0.71-0.95) with maximum magnitude at X = H. A concerted mechanism involving predominant backside nucleophilic attack is proposed on the basis of the secondary inverse DKIEs.
