The compound in the title was prepared by reaction between tryptamine and ibuprofen using N,N′-dicyclohexylcarbodiimide as a “dehydrating” reagent. The structure of the newly synthesized compound was determined by nuclear magnetic resonance (NMR) (1H-NMR and 13C-NMR), UV, IR, and mass spectral data.

The AlCl3 catalyzed reaction of 1,1-d2-1-chloropropane with benzene was carried out in excess benzene at about 5° or in 1,2,4-trichlorobenzene as solvent at 0°. The products, n-propylbenzene and isopropylbenzene, were examined by nuclear magnetic resonance and mass spectrometry. The results indicated only very minor amounts of isotope position scrambling in the propyl side chain, suggesting no major involvement of protonated cyclopropane intermediates in the reaction. The mass spectral data, however, demonstrated that the products are quite labile in the reaction medium, with extensive intermolecular hydride and deuteride transfers taking place.

Tanaman mangga (Mangifera indica L.) adalah tanaman berbuah musiman yang banyak terdapat di Indonesia. Secara umum, daun tanaman ini mengandung saponin, alkaloid, fenol, tannin, flavonoid, steroid, diterpene dan glikosida. Senyawa metabolit sekunder yang umum ditemukan dalam tanaman ini adalah mangiferin (2-C-β-D-glucopyranosyl-1,3,6,7-tetrahydroxyxanthone), yang termasuk dalam golongan polifenol. Mangiferin memiliki beberapa aktivitas seperti antikanker, antiinflamasi, antidiabetes, dan antihiperlipidemia. Artikel ini membahas teknik isolasi mangiferin dan elusidasi strukturnya yang dilakukan dengan kombinasi spektrofotometri infra merah, Kromatografi Cair-Spektroskopi Massa (Liquid Chromatography-Mass Spectrometry/LC-MS), dan spektroskopi Resonansi Magnetik Inti (Nuclear Magnetic Resonance/NMR) baik berupa 1H-NMR ataupun 13C-NMR. Metode yang digunakan adalah review pustaka dengan pustaka yang digunakan sebanyak 34 artikel yang berasal dari jurnal internasional. Hasil yang didapatkan yaitu isolasi mangiferin dari tanaman mangga dapat dilakukan dengan metode refluks, soxhletasi, partisi tiga fase atau dengan bantuan microwave. Dari hasil tersebut, ditemukan bahwa ekstraksi dengan bantuan microwave memberikan persentase mangiferin lebih tinggi dari metode lain. Tetapi, penggunaan skala besar masih jarang dilakukan karena kemampuan penetrasi microwave yang rendah sehingga ada kemungkinan pemanasan kurang merata.

The coupling of diazotized 2-aminobenzothiazole with 1,3- dicarbonyl compounds (benzoylacetone, methylacetoacetate and acetoacetanilide) yielded a new series of tridentate ligand systems (HL). Analytical, IR, 1H-NMR, 13C-NMR and mass spectral data indicated that the compounds exist in the intramolecularly hydrogen bonded azo-enol tautomeric form in which one of the carbonyl groups of the dicarbonyl moiety had enolised and hydrogen bonded to one of the azo nitrogen atoms. The compounds formed stable complexes with Ni(II), Cu(II) and Zn(II) ions. The Cu(II) complexes conform to [CuL(OAc)] stoichiometry while the Ni(II) and Zn(II) complexes are in agreement with [ML2] stoichiometry. Analytical, IR, 1H-NMR, 13C-NMR and mass spectral data of the complexes are consistent with the replacement of the chelated enol proton of the ligand with a metal ion, thus leading to a stable sixmembered chelate ring involving a cyclic nitrogen, one of the azo nitrogens and the enolate oxygen. The Zn(II) chelates are diamagnetic while Cu(II) and Ni(II) complexes showed a normal paramagnetic moment.

The coupling of diazotized 2-aminothiazole and 2-aminobenzo-thiazole with cyclohexane-1,3-dione yielded a new type of tridentate ligand systems (HL). Analytical, IR, 1H NMR, 13C NMR and mass spectral data indicate the existence of the compounds in the intramolecularly hydrogen bonded azo-enol tautomeric form. Monobasic tridentate coordination of the compounds in their [CuL(OAc)] and [ML2] complexes [M = Ni(II) and Zn(II)] has been established on the basis of analytical and spectral data. The Zn(II) chelates are diamagnetic while Cu(II) and Ni(II) complexes showed normal paramagnetic moment.
