Diazoketone (13), prepared by standard methods from 5-formyl-8-methoxy-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid (7), was cyclized in trifluoroacetic acid to dienone (1) which under-went intramolecular 1,4-conjugate addition to afford the ethanophenanthrene derivative (15). Refunctionalization furnished dibenzoyloxy diacid (19) which cyclized in sulfuric acid specifically to the 8-carboxy-10,12-dibenzoyloxyperhydro-1H-2,10a-ethanophenanthrene-8,4b-carbolactone (2). Further refunctionalization to ketone (22), then formation of diazoketone (23) followed by photolysis in an aqueous medium, finally gave (1RS,4aRS,4bRS,7SR,8SR,9aSR,10SR,10aRS)-8-benzoyloxy-4a-hydroxy-1-methoxymethyloxymethylgibbane-1,10-dicarboxylic acid 1,4a-lactone (3) which may serve both as a model and intermediate for a radically new approach to the total synthesis of gibberellins.

Potato Peels

The removal of Cd(II) and Pb(II) ions from aqueous medium was studied using potato peels biomass. The adsorption process was evaluated using Atomic Absorption Spectrophotometer (AAS). The Vibrational band of the potato peels was studied using Fourier Transform Infrared Spectroscopy (FTIR). The adsorption process was carried out with respect to concentration, time, pH, particle size and the thermodynamic evaluation of the process was carried at temperatures of 30, 40, 50 and 60(0C), respectively. The FTIR studies revealed that the potato peels was composed of –OH, -NH, –C=N, –C=C and –C-O-C functional groups. The optimum removal was obtained at pH 8 and contact time of 20 min. The adsorption process followed Freundlich adsorption and pseudo second-order kinetic models with correlation coefficients (R2) greater than 0.900. The equilibrium adsorption capacity showed that Pb(II) ion was more adsorbed on the surface of the potato peels biomass versus Cd (II) ion (200.91 mg/g > 125.00 mg/g). The thermodynamic studies indicated endothermic, dissociative mechanism and spontaneous adsorption process. This study shows that sweet potato peels is useful as a low-cost adsorbent for the removal of Cd(II) and Pb(II) ions from aqueous medium.
