Radermachol and naphthoquinone derivatives from Tecomella undulata: Complete 1H and 13C NMR assignments of radermachol with the aid of computational 13C shift prediction

Petroleum ether extract of the heartwood of Tecomella undulata affords radermachol, an unusual rare pigment and
2-isopropenylnaphtho[2,3-b]furan-4,9-quinone along with lapachol, tecomaquinone-I, dehydro-α-lapachone, α-lapachone, β-lapachone, cluytyl ferulate, stigmasterol and β-sitosterol. Radermachol and 2-isopropenylnaphtho[2,3-b]furan-4,9-quinone
are being reported for the first time from genus Tecomella.
Complete assignments of 1H and 13C NMR signals of polyketide, radermachol 1, have been achieved by the 13C NMR chemical shift prediction using ab initio MO and DFT/GIAO methods in addition to 2D-NMR techniques.

Chemical constituents of Limnophila indica

 

 

Isolation and structural elucidation of two novel flavonoids, 5,6-dihydroxy-7,8,4'-trimethoxyflavone 1 and 5,2'-dihydroxy-8,3',4'-trimethoxyflavone 2, together with three known compounds, 5-hydroxy-7,2'-dimethoxy flavone 3, 5,2'-dihydroxy-7,8-dimethoxyflavone 4, and b-sitosterol 5 from the aerial parts and roots of Limnophila indica have been reported.

Effect of aniline in methanol and benzene mixture An ultrasonic study

Sound velocity, density and viscosity values have been measured at 303 K in the ternary system of aniline + methanol + benzene. The results are interpreted in terms of molecular interaction between the components of the mixtures.

1915

Synthesis of dibenzo -18- crown -6 ether containing pyrimidine derivatives

 

The strategy employed for the synthesis of new macromolecules containing pyrimidine moiety involved the acetylation of dibenzo-18-crown-6 (1) to yield 4,4- diacetyl derivative of dibenzo-18-crown-6 (2), which was further reacted with different aldehydes to give the corresponding chalcone 3. Reaction of chalcones 3 with guanidine hydrochloride give the target molecules 4. The structures of synthesized compounds have been established on the basis of spectroscopic data.
