Isoquinolin-Yl-Arylmethanone Synthesis Report
Like isoquinoline, quinoline also coupled effectively with substituted benzoyl under identical conditions. The reaction went to completion in 2 h and the desired acyl addition product, 5a, was obtained in 76% yield (Scheme 4, Table 3)
A plausible mechanism for the synthesis of an isoquinolin-1-yl-arylmethanone is depicted in Scheme 5. The synthetic cycle is assumed to begin with the reaction of Aliquat 336 as the phase transfer catalysis and K2S2O8 as a dehydrogenative reagent to generate the salt A, which then would convert to the sulfate radical B by heating. Sulfate radical B could react with the benzyl alcohol 1a through a hydrogen abstraction process providing an acyl radical C. Further addition of acyl radical C to the isoquinoline 1a

Grignard Reaction Lab
397 Words | 2 PagesGrignard is a reaction that is crucial to forming the new carbon-carbon bond. This is a two-part lab that teaches new techniques; the purpose of this lab is to introduce realistic organic synthesis and apply acid workup to produce triphenylmethanol. A Grignard reaction is characterized by the addition of a magnesium halide (an organomagnesium halide) to an aldehyde or a ketone in order to form a secondary or tertiary alcohol. These reactions are helpful because they serve as a crucial tool in performing important carbon-carbon bond-forming reactions (Arizona State University, 2018). This experiment aimed to observe the mechanisms of a Grignard reply to synthesize triphenylmethanol from benzophenone using phenylmagnesium bromide as the Grignard reagent.
Quinones: The Xalisco Drug
1631 Words | 7 PagesThe Xalisco were so desperate at times to make sure their product was known, they would sometimes give it away for free. On women that Quinones met outside of Columbus said that she didn't have any money to put more black tar. When a driver called her to see why she hadn't bought anything in three days, she explained how she didn't have any money. Shortly after their phone call, and drive showed up at the woman's home and gave her fifty dollars worth of heroin for free (167) She told Quinones “he wanted to keep me using, and buying from him” (168). Addicts like the idea of black tar because it was a lot easier to get their hands on then pills.
Synthesis Of Vanillin Lab Report
472 Words | 2 PagesThe purpose of this lab is to determine the specific isomer of the bromovanillin produced. In this experiment, vanillin is brominated to produce a mixture of isomers or one single isomer of bromovanillin. The possible product(s) formed are 2-bromovanillin, 5-bromovanillin, and 6-bromovanillin, as seen in Figure 1.1 By utilizing the bromination process of vanillin, one bromovanillin isomer can be formed as a result. As the starting material, vanillin can work with various electrophilic aromatic substitution reactions, due to the presence of aromatic double bonds within the structure.
Isopentyl Acetate Synthesis Lab Report
539 Words | 3 PagesIn this laboratory experiment, 3.030 g of Isopentyl Acetate was synthesized and formed by the esterification of acetic acid with Isopentyl Alcohol. 1.0 mL of Sulfuric acid was used as a catalyst in the reaction. The excess Isopentyl Acetate was used to shift the reaction to the right for esterification to occur. During the extraction, the excess of acetic acid and Isopentyl alcohol was extracted with sodium bicarbonate, and further purification of the Isopentyl acetate was done after through drying with anhydrous sodium sulfate and through simple distillation. The percent yield of the Isopentyl Acetate was 46.6 percent with a theoretical yield of 6.502g. In this laboratory experiment the acetic acid was in excess and the Isopentyl Alcohol was the limiting reagent,
Alkyl Bromide And Ketone Lab Report
843 Words | 4 PagesThe purpose of this experiment was to identify the unknown alkyl bromide and ketone using a Grignard reaction and IR spectrum. Also, retrosynthesis analysis was used to determine the success of identifying starting material. The organometallic compounds have a carbon-metal bond that is used to create alcohol and to expand chains of carbons. Grignard reagents, a part of organometallic ionic compounds, are widely used in organic synthesis because they are considered strong base, strong base carbon nucleophile, and soluble in many organic solvents. Results: Alkyl bromide #24 and alkyl ketone
Over Three Decade Of Synthetic Organic Chemistry Summary
481 Words | 2 PagesIn the talk, “Adventures in Organic Chemistry – Over Three Decades of Synthetic Organic Chemistry” presented by Dr. Chris Condeiu, he tried to relate the industry of organic chemistry to a students’ perspective. Three major points were drawn out through the talk. The first was the perspective of how capitalism drives the industry and the mechanism of doxycycline was formed. With an overview of his talk, the expectation was that a deeper understanding of how pharmaceutical drugs’ mechanisms are formed; instead, an insight of how the pharmaceutical industry can make one prosperous or just benefit the industry as a whole. Starting with the point about how capitalism governs the pharmaceutical industry, this relates to society in general.

Methyl Trans-Cinnamate Lab Report
1399 Words | 6 PagesIt is understood the mechanism is acid-catalyzed where protons coordinate with the carbonyl oxygen to make the carbonyl carbon more electropositive for nucleophilic attack (Scheme 1). In the experimental procedure all reactants were added together, this is inefficient as the protons can coordinate with either trans-cinnamic acid or methanol. Coordination with methanol is unnecessary as it reduces its nucleophilicity and makes less protons available to coordinate with the carboxylic acid. To improve
Benzoin Synthesis Lab Report
969 Words | 4 PagesBenzoin was oxidized to benzil by copper (II) which is formed from cupric acetate. The yield will be lower when benzoin oxidized with copper then it converted into benzoil. Students should know ammonium nitrate, cupric acetate, and acetic acid function. Firstly, copper (II) from cupric acetate will separate and gain an electron from benzoin. Therefore, benzoin became the radical cation.
Tans-Atovaquone

The quinine group of ubiquone gets reduced to the quinol and helps in transferring the electron through an oxidation reduction cycle (Tielens A G M and Hellemond J J V 1998; Kroger A. and Gwith M K 1973). Atovaquone too has a quinine group and thus, it can mimic ubiquone and binds selectively to the Q0 site of parasitic mitochondria thereby block the parasitic mitochondrial respiration (Ridley R G 2002). In the present study, we report binding characteristics of trans and cis-isomers of atovaquone with cytochrome bc1 of yeast using docking technique in order to address the basic question, why trans isomer of atovaquone has much higher drug potency than that of its cis isomer?
Quinazolinones Research Paper
725 Words | 3 PagesHeterocyclic chemistry comprises at least half of all organic chemistry research worldwide. Quinazolinones are the versatile nitrogen containing heterocyclic compounds. Earlier it is known as benzo-1,3-diazine and was first prepared in laboratory by Gabriel in1903 and first isolated from the chinese plant aseru.1 The name quinazoline (German : Chinazolin) was first prepared by Weddige, on observing that this was isomeric with the compounds cinnoline and quinoxaline. Paal and Bush suggested the numbering of quinazoline ring system, which is currently used.2 Quinazolinones will be classified into the following five categories based on the substitution patterns of the ring system.3 • 2-substituted-4(3H)-quinazolinones • 3-substituted-4(3H)-quinazolinones
