Spectroscopic and biocatalytic properties of a chlorophyll-containing extract in silica gel

UV-Vis absorption and fluorescence spectra of chlorophyll a (in the form of spinach extract) in acetone solution and in silica gel showed a predominance of pigment dimers in its overall concentration and an evident transformation of chlorophyll a to pheophytin with time. The dimerization constant of chlorophyll a in acetone was log Kdim = 2.14, whereas the constants for chlorophyll a and pheophytin a in alcogel were log Kdim = 4.70 and log Kdim = 5.22, respectively. Biocatalytic experiments indicated the possibility of using the pigment embedded in silica gel, i.e. mainly its dimeric form, for biotransformation of α-pinene to pinocarveyl hydroperoxide, trans-pinocarveol, pinocarvone and myrtenal. The advantage of a heterogeneous biocatalytic system (composed of a solvent and silica gel) over a homogeneous system (single phase of chloroform) is the possibility of reusing the biocatalyst with about 10% preservation of its activity.

PINENE-DERIVED DIISOCYANATES

A pinene-derived diisocyanate compound, a process for forming a pinene-derived diisocyanate compound, and an article of manufacture containing a polyurethane polymer are disclosed. The process for forming the pinene-derived diisocyanate compound includes oxidizing the pinene to form a pinene-derived ketone compound, converting the pinene-derived ketone compound to a diamine compound in subsequent reaction steps, and reacting the diamine compound with phosgene to form the pinene-derived diisocyanate compound. The polyurethane polymer is synthesized in a reaction between a pinene-derived diisocyanate compound and a polyol.

Allylic oxidation of cyclic alkenes with molecular oxygen and tert-butyl hydroperoxide over copper-manganese oxides

Abstract: An efficient and mild method for the allylic oxidation of cyclic alkenes employing molecular oxygen and tert-butyl hydroperoxide as the oxidant, copper-manganese oxides as heterogeneous catalyst under ambient temperature is proposed. The catalyst, which was prepared by co-precipitation and characterized, was evaluated oxidation of isolongifolene as a typical mode substrate. The catalyst showed a good catalytic activity and remained nearly the same after four cycles. The scope of the reaction was investigated with a variety of cyclic alkenes compounds.
