In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Formula: C12H12O4, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 50551-57-0, name is Ethyl 6-methoxybenzofuran-2-carboxylate. In an article，Which mentioned a new discovery about 50551-57-0
The first total chemical synthesis of a cis-syn furan-side photoproduct between a psoralen derivative and thymidine is described. The key step in the synthesis was an intramolecular [2 + 2] photocycloaddition, which directed the stereochemical course of the reaction to afford a product equivalent to that formed when a psoralen molecule is allowed to react at a 5′-TpA-3′ site in DNA. A model system consisting of a simple benzofuranyl acid tethered to the 5′ hydroxyl of thymidine showed that it was possible to bias the stereochemical outcome of the photochemical reaction in favor of the desired cis-syn product. Further refinement of the model system allowed for the elaboration of a benzofuran-thymidine photoproduct into a cis-syn 2-carbomethoxypsoralen furan-side thymidine monoadduct. The stereochemistry of all photoproducts as established by NMR and CD spectroscopy indicated that the cycloadditions occurred on the 3′ face of thymine, the equivalent of a psoralen monoadduct in a 5′-TpA-3′ site in DNA. Previously, the inability to program the sequence context of psoralen-DNA adducts has constrained certain biological studies, such as experiments aimed at deciphering the transcriptional effects of adducts at TATA sites. This method is a key step toward overcoming that problem.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 50551-57-0, help many people in the next few years.Formula: C12H12O4
