Multi-component Process for the Synthesis of Some Phosphonate Derivatives using Water as a Green Solvent
A novel, convenient and efficient multi-component reaction for synthesis of phosphonate derivatives from activated acetylenic compounds with 2-hydroxyacetophenone in the presence of phosphites in water lead to the formation of phosphonates in good yields.
متن کاملSynthesis of Pyrrole Phosphonate Esters: Emphasis on Pyrrole NH Acids and Dialkylacetylenic Esters Substitution
Reaction of dialkyl acetylenedicarboxylates 1a-c andpyrrole derivatives 2a-e in the presence of triphenylphosphite (TPP) was investigated and the effect of the pyrrole substitution was established. Diastereoselectivity is observed with pyrroles, 2a,b, yieldingphosphonate ester derivatives 3a-f and 4,and their relative configuration is determined by 1H/13C and 31</...
