Proline-modified DNA as catalyst of the aldol reaction.
DNA templated synthesis has emerged as a powerful tool to steer reactivity by modulating nature s approach to increase the effective molarity of the reactants. By making recourse to the inherently selective duplex formation properties of cognate DNA strands, small molecule reactants are brought to close proximity increasing the effective molarity and thereby significantly accelerating chemical ...
متن کاملAn efficient aldol-type direct reaction of isatins with TMSCH2CN.
Cesium fluoride catalyzed direct cyanomethylation of various isatins by using trimethylsilyl acetonitrile (TMSAN) as a nucleophile has been developed. The reaction has been explored for a number of isatins, with various substitutions on its aromatic ring. Further, the versatility of the reaction is demonstrated by converting the direct aldol adducts to the corresponding intermediates of natural...
متن کاملNanoZnO as an efficient & reusable catalyst for the preparation of 1,4-DHPs via Hantzsch reaction
Easily prepared nanoZnO was found to be as an efficient catalyst in the synthesis of 1,4-DHPs via four-component reaction of 1,3-dicarbonyls, aldehydes and ammonium carbonate in water at 60 °C. The prepared nanoZnO was characterized by XRD and FT-IR analysis, while the determined specific surface area of nano catalyst by BET method was 33 m2/g.
