A New Route to 4-Unsubstituted β-Lactams through Ureidomethylation of Ketene Silyl Acetals
スポンサーリンク
概要
- 論文の詳細を見る
α-Ureidomethylated carboxylates were obtained by the reaction of ketene silyl acetals with benzyl N-(chloromethyl) carbamates in the presence of titanium tetrachloride. Successive hydrogenolysis over palladium-on-charcoal followed by treatment with lithium diisopropylamide gave β-lactams.
