Application of H2O as the Green Solvent for the Synthesis of Phosphonates via Multicomponent Reactions
Phosphonate derivatives were prepared using multicomponent reactions of dialkyl acetylenedicarboxylate with 4-hydroxycumarine in the presence of trimethyl or triphenyl phosphite in good yields.
متن کاملNew synthesis and reactions of phosphonates
The importance of phosphorus can be highlighted not only through its biological significance, but also in its many varied industrial, medicinal, and synthetic applications. Phosphonate moieties in particular have broad applications including their use as reagents in the Horner-Wadsworth-Emmons olefination reaction, a widely used synthetic strategy. As an alternative to the often harsh condition...
متن کاملThe asymmetric synthesis of chiral cyclic α-hydroxy phosphonates and quaternary cyclic α-hydroxy phosphonates.
A highly practical, catalytic enantioselective cyclic phosphite addition to aldehydes and ketones was developed. The reaction rate of the asymmetric hydrophosphonylation was significantly enhanced by the addition of silver carbonate. Particularly, significant improvement has been achieved on the asymmetric hydrophosphonylation of unactivated ketones, giving quaternary α-hydroxy phosphonates wit...
متن کاملBetulin Phosphonates; Synthesis, Structure, and Cytotoxic Activity.
Betulin derivatives are a widely studied group of compounds of natural origin due to their wide spectrum of biological activities. This paper describes new betulin derivatives, containing a phosphonate group. The allyl-vinyl isomerization and synthesis of acetylenic derivatives have been reported. Structural identification of products as E and Z isomers has been carried out using ¹H-, (13)C-, (...
