چکیده
The ®rst of the title compounds, C31H27NO4S, (V), crystallizes in the monoclinic space group P21/c with two independent molecules in the asymmetric unit, while the second, C23H27Cl2NS, (IX), crystallizes in the orthorhombic space group Pbca with one molecule in the asymmetric unit. In both crystal structures, the 1,3-thiazolidine ring adopts a half-chair conformation. The crystal structures are stabilized by weak CÐH O and CÐH Cl hydrogen bonds in (V) and (IX), respectively.

Design, Synthesis and Characterization of Some Novel 3-Coumarinyl- 5-aryliden-1,3-thiazolidine-2,4-diones and Their Antioxidant Activity
In our effort to obtain biologically active compounds, new 3,5-disubstituted 1,3-thiazolidine-2,4diones (5a – r) were synthesized. A series of 5-arylmethylidene-1,3-thiazolidine-2,4-diones (3a – r) were prepared by Knoevenagel reaction from 1,3-thiazolidine-2,4-dione (2) and appropriate aromatic aldehydes. Condensation of 3a – r with 7-hydroxy-4-bromomethyl-2-oxo-2H-chromene (1) afforded novel ...
متن کاملSynthesis and anticonvulsant activity of new 3'-aryl- 7-bromo-spiro[ [1]benzothiophene-3,2'-[1,3] thiazolidine]-2,4'-dione derivatives
Two series of spiro[ [1]benzothiophene-3,2'-[1,3]thiazolidine]-2,4'-diones 5a-e and 6a-e were synthesized, characterized and evaluated for anticonvulsant activity. Reaction of [1]benzothiophene-2,3-dione (3) with certain arylamines afforded the corresponding Schiff bases 4a-e. Cyclization of 4a-e with thioglycolic or thiolactic acids brought about the target spiro compounds 5a-e and 6a-e respec...
متن کاملSynthesis, Semiempirical, Stereoselectivity and Pharmacological Activity of a New Class of Spiro Pyrrolidine and Isoquinoline Derivatives
1,3-Dipolar cycloaddition of azomethine ylides derived from acenaphthylene-1,2-dione and 5methyl-benzo[b]-thiophene-2,3-dione with L-proline, thiazolidine-4-carboxylic acid and 1,2,3,4tetrahydroisoquinoline-3-carboxylic acid with various electron deficient dipolarophiles leads to the formation of novel spiroheterocycles having two or more chiral centers. Semiempirical studies have been performe...
متن کاملExperimental and theoretical study of the structures and enthalpies of formation of the synthetic reagents 1,3-thiazolidine-2-thione and 1,3-oxazolidine-2-thione.
This paper reports an experimental and a theoretical study of the structures and standard (p(o) = 0.1 MPa) molar enthalpies of formation of the synthetic reagents 1,3-thiazolidine-2-thione [CAS 96-53-7] and 1,3-oxazolidine-2-thione [CAS 5840-81-3]. The enthalpies of combustion and sublimation were measured by rotary bomb combustion calorimetry, and the Knudsen effusion technique and gas-phase e...
