ChemInform Abstract: γ-Silylated α,β-Unsaturated Amides — Preparation by [1,5]-Sigmatropic Rearrangement and Use as Masked Dienolate Equivalents in Carbonyl Condensations

The reaction of lithium dienolates derived from N,N-dialkylsenecioamides (1a–1c) with triorganosilyl electrophiles occurs initially at the oxygen atom predominantly, and is followed by an O → C sil...
