For one to be able perform this acylation technique‚ there are two mar approaches which are employable. The first method involves the deprotonation of the α-Carbon atom which has a pKa known to be ̴20 through the use of a strong base for instance

Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared

of MPTP dramatically accelerates this process in the course of days and not years (Hanson et al.‚ 2015). Additionally consumption results in a reduction of glutathione content (Sian et al.‚ 1999). What have been good and bad consequences of the synthesis of MPTP? MPTP negatively affects the body by penetrating the blood-brain barrier and entering the brain cells. MPTP is not toxic‚ however when it oxidizes it forms MPP+ which is toxic. Toxic oxidation later reaches the extracellular fluid and
