Preparation of the Phencyclidine Analogues (Part II)
Using a-tetralone, as starting material, a series of phencyclidine analogues were synthesized. This ketone was reacted separately with ethylmagnesium bromide, P-methoxyphenylmagnesium bromide and P-methylphenylmagnesium bromide. The resultant alcohols were treated with a suspension of NaN3 and CCl3COOH in CHCl3. The azides were subsequently...
متن کاملThe Kinetics of Tripropylammonium Fluorochromate Oxidation of Mandelic Acids
The oxidation of Mandelic Acids (MA) to the corresponding oxoacids with tripropylammonium fluorochromate (TriPAFC) in aqueous acetic acid has been studied. The reaction is first order with respect to [TriPAFC], [MA] and [H+]. The oxidation of α-deuteriomandelic acid shows the presence of a primary ki...
متن کاملOxidation of the Amino Acids: Ii. Alanine and Tyrosine
Two grams of Kahlbaum’s alanine dissolved in 50 cc. of water were oxidized with 500 cc. of a solution containing 10.8 grams of potassium permanganate and 37.0 grams of potassium hydroxide (30 molecules). Vigorous oxidation took place at once and the temperature of the mixture rose to 37” C. After standing for forty-eight hours at room temperature complete decolorization had taken place; the pro...
متن کاملSelective Oxidation of Xylenes to Toluic Acids
A mixture of manganese, cobalt and lead para-amino benzoates supported on silica gel is used to catalyze oxidation of xylenes to toluic acids in presence of oxygen or air. Reactions are clean and catalysts can be recovered easily and reused.
متن کاملHydroxylation and decarboxylation of hydroxybenzoic acids by Fe -chelates
4 2 containing FeSO and Na EDTA. EDTA could be replaced by citric acid. In this in vitro system 4hydroxybenzoic acid is hydroxylated to 3,4-dihydroxybenzoic acid (protocatechuic acid) and decarboxylated to hydroquinone. In an analogous reaction 2-hydroxybenzoic acid (salicylic acid) is hydroxylated to 2,3-dihydroxybenzoic acid and 2,5-dihydroxybenzoic acid (gentisic acid) and decarboxylated to ...
