A practical carbamoylsilane-based synthesis of β-arylidene <em>N</em>-methoxymethyl α-siloxy carboxamides from α,β-enones

Using <em>N</em>-methoxymethyl-<em>N</em>-methylcarbamoylsilane as potent secondary amide source, the direct transformation of β-aryl-α,β-enones into the corresponding <em>N</em>,<em>N</em>-disubstituted β-arylidene α-siloxy carboxamides <em>via</em> the aminocarbonylation reaction is described. The reactions provide good yields of the products under simple and catalyst-free conditions.
