A series of novel α-(diphenylphosphoryl)- and α-(diphenylphosphorothioyl)cycloalkanone oximes have been synthesized in search for novel bioactive molecules. Their structures were characterized by various spectroscopic methods including IR, NMR ( 1 H, 31 P, 13 C), mass spectrometry and single crystal X-ray diffraction. The newly synthesized phosphorus-containing oximes were screened for their in vitro

First organophosphorus derivatives of 2-alkyl-and 2,3-alkylene-substituted 1,8-naphthyridines were synthesized by the Friedländer reaction starting from 2-aminonicotinaldehyde and diphenylphosphoryl(cyclo)alkanones, respectively.
A simple and convenient copper‐catalyzed directoxyphosphorylation of enamides with P(O)‐H compounds and dioxygen has been developed under mild conditions. This methodology can allow the synthesis of a series of valuable β‐ketophosphine oxides/β‐ketophosphonates in moderate to good yields with a broad substrate scope simply by using readily‐available starting materials.

A straightforward regio- and diastereoselective process has been developed for the synthesis of unprecedented symmetrical trans-α,α′-bis(diphenylphosphoryl)- and α,α′-bis(diphenylphosphorothioyl)-cycloalkanones, through the reaction of cyclic enamines with excess P-chlorodiphenylphosphine in the presence of triethylamine, followed by oxidation or sulfurization and hydrolytic workup.

ACTION DES ENAMINES SUR LES MONOCHLOROPHOSPHINES: SYNTHESE DES β-CETOPHOSPHONATES
Abstract In recent years β-phosphoryl ketones were considered as valuable intermediates in organic synthesis. In the present work we studied the reaction of enamines 1 with monochlorophosphine 2 which led to the β-phosphinoyl cycloalkanones 3. The structure of products 3 was confirmed by NMR and IR spectroscopy.
