The key attribute of the thiol-Michael addition reaction that makes it a prized tool in materials science is its modular “click” nature, which allows for the implementation of this highly efficient, “green” reaction in applications that vary from small molecule synthesis to in situ polymer mo...
Lewis acid, Me 3 SiOTf, has been shown to be a promising promoter for aza-Michael reaction of relatively acidic primary amide with α,β-unsaturated ketone. A sries of α,β-unsaturated ketones was transformed to their corresponding β-amido ketones with moderate yields under this reaction cond...
