Abstract

Synthesis of novel Sultams containing azetidinone heterocycles

Author(s): P. Ramesh Babu, L. K. Ravindranath and D. Rajesh

Novel Azetidinones Synthesis of 3-chloro-1-(2-(1,1-dioxido-1,2-thiazetidin-2-yl)ethyl)-4-substituted phenylazetidin- 2-one7(a-f) were synthesized by condensation reaction between synthesis of 2-(2-(4-substituted benzylideneamino)ethyl)-1,2-thiazetidine 1,1-dioxide 6(a-f) and a mixture of mono chloro acetyl chloride and ethyl amine. Synthesis of 2-(2-(4-substituted benzylideneamino)ethyl)-1,2-thiazetidine 1,1-dioxide 6(a-f) was condensed with 4-substituted benzaldehyde in absolute alcohol. The synthesis of 2-(2-aminoethyl)-1,2-thiazetidine 1,1- dioxide(4) was synthesized by condensation of synthesis of 1,2-thiazetidine 1,1-dioxide (β-Sultam)(3) a mixture of K2CO3, TEBA , Acetonitile and 2-chloro ethanamide. Synthesis of 1,2-thiazetidine-1,1-dioxide(β-Sultam) (3) was synthesized with Taurinesulfonylchloride (2) with Na2CO3, Ethyl acetate. Taurinesulfonylchloride (2) was synthesized by S-S bond cleavage Cystaminedihydroxychloride (1) with mixture of Chlorine gas, Chloroform and Ethanol solvent mixture.
