The second type is “artificial”, which as the name suggests, are created by completely artificial means. The sources of artificial flavors are often inedible, such as petroleum. Octyl acetate, a chemical that dominates the tangy taste of an orange, can be synthesized in a lab and simply ad...
As the dramatically increased acidity of naphthol in the singlet excited state would be expected to significantly accelerate the heterolytic CH2–O bond cleavage reaction,16 2-arylmethyloxy-6-cyanonaphthalenes were synthesized as prospective photoinitiators. An analysis of the product distribution ...
di- and tri-O-acetylated neuraminic acids before and de-O-acetylated neuraminic acids after treatment of mucin from bovine submaxillary glands with bacteria-derived O-acetyl esterases revealed the extent of O-acetylation and carbon positions of the acetate esters using ESI-MS analysis (Feuerbaum ...
asynthesized by means of Wittig–Horner reactions between appropriate dibenzyloxybenzylphosphonic acid diethylesters(5a,b) and benzyloxybenzaldehydes (6a-c), followed by deprotection using AlCl3 and N,N dimethylaniline as outlined in Scheme 2. Trans geometries of these compounds were confirmed by their...
A series of structurally related oxprenolol esters were synthesized and investigated as potential prodrugs for improved ocular use. The stability of each ester was studied in phosphate bufC. GeraldineDepartment of Food ScienceM. JordanDepartment of Food ScienceJournal of Pharmaceutical Sciences...
We synthesized esters of α-tocopherol (VE) with the aim to develop new pro-vitamins, easily reconverted by enzymes in the skin and able to release another active moiety such as an amino acid, in order to obtain a synergic effect. In particular, the attention was dedicated to the amino ...
Chevrel phase Mo6S8 was synthesized using the molten salt synthesis method as reported in the literature by Aurbach and coworkers23. MoS2 (99% Aldrich), CuS (99.5%), and Mo (99%) were obtained from Aldrich, all in powder form. The XRD patterns of in-house made CuMo6S8 and Mo6S8 ...

explosophoric group is bonded to the carbon atom of the framework through the C-O bond (as in esters of nitric and perchloric acids, see entries 2 and 13), the heat effect of the redox reaction is reduced, since part high-strength C-O bonds are already there before the start of the...
It provides a broad range of antioxidants including tocotrienols, which have been found to be six thousand times more effective than vitamin E. Also natural B-Vitamins that boost energy, stamina and help stabilize blood sugar. (Including natural B-Vitamins that cannot be synthesized such as Pangam...
