    more readily absorbed by mouth.[9] There are 2 isoforms of CYP450 in the liver involved in codeine’s phase 1 metabolism: CYP2D6‚ activating 5-10% codeine to generate morphine in an O-demethylation reaction and CYP3A4‚ activating 10% of codeine to an inactive metabolite‚ norcodeine. The former reaction is comparably slower to the latter‚ resulting in codeine being deactivated faster than it’s activated. The CYP2D6 enzyme is genetically polymorphic‚ and 5-10% of the population have decreased CYP2D6

    Acid Discussion: In this experiment‚ benzoin was oxidized by nitric acid to benzil‚ which in turn was rearranged to benzilic acid. Prior to beginning the experiment‚ the theoretical yield of benzil was discovered. The limiting reactant in the reaction‚ benzoin + nitric acid benzil‚ was benzoin at 0.00141 moles. This value was discovered by the initial amount of the reactants used: 0.30 grams benzoin and 1.5 ml Nitric Acid (see Eq 1). Using the moles of the limiting reagent benzoin‚ the theoretical

    Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

    Multistep Synthesis of Tetraphenylcyclopentadienone Author: Instructor: Date work performed: 10.18.2012--10.25.2012 Date work submitted: 11.01.2012 Abstract: The aim of this experiment was to perform a multistep synthesis to form tetraphenylcyclopentadienone. The first step of the reactions was to synthesize benzoin from the condensation of benzaldehyde. A yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1

    Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5%

    melted at 158.5-162 degrees Celsius. Introduction: Grignard reagents are the most useful way to form primary‚ secondary or tertiary alcohols from a carbonyl group. The Grignard reaction involves the nucleophilic addition of an organomagenesium complex to a carbonyl carbon followed by acid work-up. This reaction involves a single electron transfer between the carbonyl group and the grignard reagent. Once the Grignard reagent is synthesized it can work as a base by abstracting a proton or it can
