Highly enantioselective conjugate addition of AlMe3 to linear aliphatic enones by a designed catalyst
2-Hydroxy-2?-alkylthio-1,1?-binaphthy compounds are catalytic promoters of the 1,4-addition of AlMe3 to linear aliphatic enones in THF at -40 to -48C in the presence of [Cu(MeCN)4]BF4. At ligand loadings of 5-20 mol%, enantioselectivities of 80-93% are realised for most substrates. To attain these values, the use of highly pure AlMe3 is mandatory. The presence of methylalumoxane (MAO), derived by hydrolysis, leads to reduced enantioselectivity and a conjugate addition product.
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 18531-94-7, help many people in the next few years.Product Details of 18531-94-7
