Synthesis 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</...
متن کاملSolution-phase synthesis of pyrrole-imidazole polyamides.
Pyrrole-imidazole polyamides are DNA-binding molecules that are programmable for a large repertoire of DNA sequences. Typical syntheses of this class of heterocyclic oligomers rely on solid-phase methods. Solid-phase methodologies offer rapid assembly on a micromole scale sufficient for biophysical characterizations and cell culture studies. In order to produce gram-scale quantities necessary f...

متن کاملSynthesis and binding pattern of Calix[4]Pyrrole compounds
In this short review, focus has been on the improvisations in the synthetic procedures of the Calix[4] pyrrole type compounds, since their first discovery in the year 1886 and subsequent discussion on their binding pattern towards different chemical species. Calix[4] pyrrole, which is an analogue of hetero calixarenes, is the representative of a group of macrocycles. It has an ability to bind n...
متن کاملSynthesis of New Derivatives of Pyrrole Tuberculostatics Providing Structural Diversity
Nine pyrrole-containing compounds were designed introducing reasonable structural novelties within the framework of the architecture of confirmed tuberculostatics. The new products were synthesized via adopted Paal-Knorr cyclization by condensation of three 1,4-dicarbonyl compounds with a set of substituted anilines, acting as primary amines. Preliminary in vitro tests have already registered e...
