Zarei, Maaroof,Jarrahpour, Aliasghar
, p. 2572 - 2576 (2011)
Efficient conversion of Schiff bases and carboxylic acids to -lactams can be carried out at room temperature in CH2Cl2, using a cyanuric chloride-N,N-dimethyl formamide complex. The complex is easily prepared by reaction of cyanuric
Efficient one-pot synthesis of 2-azetidinones from acetic acid derivatives and imines using methoxymethylene-N,N-dimethyliminium salt

experimental part, p. 5017 - 5023 (2010/08/19)
A cheap, versatile and convenient method for synthesis of β-lactams using methoxymethylene-N,N-dimethyliminium salt as an acid activator in Staudinger reaction is reported. This method is used for the preparation of monocyclic, spirocyclic, N-alkyl and th
The Vilsmeier reagent: a useful and versatile reagent for the synthesis of 2-azetidinones
Jarrahpour, Aliasghar,Zarei, Maaroof
experimental part, p. 2927 - 2934 (2009/05/30)
(Chloromethylene)dimethylammonium chloride (Vilsmeier reagent), prepared easily from N,N-dimethylformamide and oxalyl chloride or thionyl chloride, works as a versatile acid activator reagent for the direct [2+2] ketene-imine cycloaddition of substituted
Synthesis of β-lactams: α-chloro and α-cyano β-lactams by condensation of imines with titanium ester enolates derived from chloro and cyano ethyl acetates
