The title compound, N-benzo[c][1,2,5]thiazol-4-yl-3-trifluoromethylbenzamide (1) was synthesized by reacting 3-trifluoromethylbenzoyl chloride (4) and 4-aminobenzo[c][1,2,5]thiadiazole (5). The compound was characterized by various spectroscopic methods (1H NMR, 13C NMR, IR, GC-MS) and its composition confirmed by elemental analysis. The importance of this compound lies in its possession of an N,N-bidentate directing group. Such a structural motif is potentially suitable for metal-catalyzed C-H bond functionalization reactions.

The aerial parts of three endemic Centaurea L. species, namely C. tomorosii Micevski, C. soskae Hayek and C. galicicae Micevski, afforded sesquiterpene lactone cnicin (1) and seven flavonoids: apigenin (2), isokaempferide (3), hispidulin (4), eupatorin (5), cirsimaritin (6), santaflavone (7) and salvigenin (8). The structures of the isolated compounds were determined by UV, 1H NMR and 13C NMR spectroscopy and HR-ESI-MS spectrometry. 1H NMR spectroscopy was used as a method for quantitative analysis of sesquiterpene lactone cnicin.

Aims: Isolation of Isocarpine From Adenocarpus Complicatus. Background: Adenocarpus Complicatus L. is one of Adenocarpus genus which has about 50 species, from Fabaceae (Papilionaceae) family. This plant found in the Mediterranean basin as southern west part of Europe and North Afric forestes. Objective: Isolation of Isocarpine From Adenocarpus Complicatus as Anticandidal Agent method: A new piperidine alkaloid Isocarpine was isolated from the aerial parts of Adenocarpus Complicatus L., which gross in Syria. The structure of the new compound was determined by UV, IR, EI-Ms, 1H-NMR, 13C-NMR, DEPT-135, DQF-COSY and HMQC. Results: The anticandidal activity of isocarpine was screened against 38 Candida strains and showed remarkable inhibitory effect compared with fluconazole as antifungal reference drug. Conclusion: Isocarpine is antifungal agent.

Two known pregnane type of alkaloids, axillaridine A and spiropachysine, and an unidentified pregane alkaloid along with oleanolic acid and stigmasteryl glucoside have been isolated from chloroform extract of the aerial parts of Sarcococca hookeriana. The structures of the alkaloids are established on the basis of spectral analysis of 1H-NMR, 13C-NMR, HMQC, COSY and HMBC spectrum. All compounds were isolated for the first time from S. hookeriana. So far, species of Sarcococca was not reported to contain spiropachysine which was initially reported as a novel alkaloid from Pachysandra terminalis SIEB. et ZUCC.(Buxaceae).DOI: 10.3126/jncs.v21i0.215Journal of Nepal Chemical Society Vol.21 2006 pp.8-15
