CuCN-Mediated Cascade Cyclization of 4-(2-Bromophenyl)-2-butenoates: A High-Yield Synthesis of Substituted Naphthalene Amino Esters
摘要:
A new method of CuCN-mediated one-pot cyclization of 4-(2-bromophenyl)-2-butenoates leading to efficient synthesis of substituted naphthalene amino esters including phenanthrene aromatic structural units is described. Deuterium labeling studies establish that this one-pot cascade cyclization proceeds through isomerization of olefin, intramolecular C-C bond cyclization, and aromatization as the key intermediates, all occurring in a single step.

β,γ-Unsaturated carbonyl compounds serve as versatile building blocks in organic synthesis and medicinal chemistry. Herein we reported the synthesis of β,γ-unsaturated carbonyl compounds from tetrafluoropyridine sulfides with vinyl halides. This cross-coupling reaction takes the advantage of photocatalysis, as well as zinc catalysis, which is preferred due to its less-toxic, earth abundant, and cost-effective

In vitro antiproliferative assays still represent one of the most important tools in the anticancer drugdiscovery field, especially to gain insights into the mechanisms of action of anticancer small molecules. The NCI-DTP (National Cancer Institute DevelopmentalTherapeuticsProgram) undoubtedly represents the most famous project aimed at rapidly testing thousands of compounds against multiple tumor
