Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. SDS of cas: 63675-74-1, In an article, mentioned the application of 63675-74-1, Name is 6-Methoxy-2-(4-methoxyphenyl)-1-benzothiophene, molecular formula is C16H14O2S
Radiolabelled raloxifene (LY156758) has been prepared by tritium gas hydrogenolysis of a 3-aroyl-bis-brominated precursor. The requisite halogenated intermediate was accessed by regioselective aroylation of benzothiophene 6 with the acid chloride of 3,5-dibromo-4-[2-(1-piperdinyl)ethoxy]benzoic acid (5). Selective deprotection of the aryl methyl ethers in the presence of the ethoxy side-chain followed by palladium catalyzed halogen-tritium exchange provided the target compound with a specific activity of 30.1 Ci/mmol.
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 63675-74-1, help many people in the next few years.SDS of cas: 63675-74-1
