, p. 728 - 734 (2013)
Thiocarbonyldiimidazole has been found to be an efficient acid activator for the synthesis of-lactams by ketene-imine cycloaddition at room temperature. The experimental procedure is simple and results in excellent yields of the products. All products wer
Unprecedented stereocontrol of β-lactam formation derived from N-cinnamylidenearylamine
Banik, Bimal K.,Aguilar, Hector,Cordova, Daniel
, p. 2321 - 2324 (2008/09/18)
Formation of β-1actams by the reaction of acid chloride, N-cinnamylidenearylamine and a tertiary amine seems to involve multiple pathways. Microwave-induced irradiation and high temperature lead to preferential formation (95-100 %) of trans β-lactams deri
Synthesis of azetidin-2-ones from imines and acids using trichloroacetonitrile-triphenylphosphine reagent
Govande,Arun,Deshmukh,Bhawal
, p. 4177 - 4182 (2007/10/03)
A one step synthesis of azetidin-2-ones (3a-j) has been described by the reaction of imines (1) with acids (2) in presence of trichloroacetonitrile, triphenylphosphine and triethylamine.

, p. 353 - 362 (2007/10/02)
2-Acyl-3-oxo-4,5-benzo-1,2-thiazoline 1,1-dioxide (3) provides good yield routes to monocyclic β-lactams (6) and tricycic β-lactams (7) from a variety of imines (4) and 1-substituted-3,4-dihydroisoquinolines (5).
