Easily accessible 1-(N-acylamino)alkyltriphenylphosphonium salts react smoothly with nitrogen, sulfur, phosphorus and oxygen nucleophiles in the presence of (i-Pr)2EtN to give the expected α-amidoalkylation products, usually in good or very good yields. α-Amidoalkylation of dialkyl malonates or acetylacetates requires the application of a much stronger base (DBU) and gives the best results under the influence of microwave irradiation. α-Amidoalkylation of enamines was carried out successfully in the presence of (i-Pr)2EtN in a microwave reactor. 1-(N-Acylamino)alkyltriphenylphosphonium salts can be considered as new, convenient and effective α-amidoalkylation agents.
Synthesis of N-[1-(trialkylstannyl)alkyl]amides and -amines by the displacement of benzotriazoles with trialkylstannyllithiums
Pearson,Stevens
, p. 904 - 906 (2007/10/02)
Condensation of benzotriazole, an aldehyde, and either an amine or amide using the method of Katritzky gave N-[1-benzotriazol-1-yl)alkyl]amides and -amines, which were treated with tributylstannyllithium or trimethylstannyllithium to afford N-[1-(trialkylstannyl)alkyl]amides and -amines, respectively. These compounds are important precursors of nitrogen-substituted organolithium reagents.
The Chemistry of Benzotriazole. Part 3. The Aminoalkylation of Benzotriazole
Katritzky, Alan R.,Rachwal, Stanislaw,Rachwal, Bogumila
, p. 799 - 804 (2007/10/02)
1-(1-Hydroxyalkyl)benzotriazoles convert a wide variety of aromatic and heteroaromatic primary amines into their mono N- derivatives in high yield.Aliphatic primary amines frequently give bis-derivatives.Product structure is established by 13C n.m.r.; dangers in the use of 1H n.m.r. to distinguish 1- and 2-substituted benzotriazoles are pointed out.
