The synthesis of phosphonic acids derived from homocysteine via transesterification reactions

Synthesis of Phosphorus Derivatives via Multicomponent Reactions

Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields. 

New strategy for the synthesis of functionalized phosphonic acids

Various approaches leading to mono-, diand poly-functionalized phosphonates as well as phosphoryl heterocycles were reported for the systematic study of relationship between chemical structure and biological activities of this most important class of organophosphorus compounds. Introduction Functionalization of phosphonic acid molecules opens enoi-nious possibilities of structural variation of ...

Synthesis of sugar-derived spiroaminals via lactamization and metathesis reactions.

A series of sugar-derived spiroaminals has been synthesized by utilizing cross metathesis, ring closing metathesis and lactamization reactions as key steps from 1-C-alkylated glycosyl azides and important correlations in the spectral data between spiroaminals and their respective anomers are reported.

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.
