- 7. Quinolines, heterocyclic compounds that contain a pyridine ring fused to a benzene ring, are commonly synthesized by a method known as the Skraup Synthesis, in which aniline reacts with glycerol under acidic conditions. Nitrobenzene is added to the reaction mixture to serve as an oxidizing agent. The first step in the synthesis is the dehydration of glycerol to propenal. What starting materials are needed for the synthesis of 2,7- diethyl-3-methylquinoline? Hint: Figure out the mechanism of the synthesis. quinolinearrow_forwardOct-1-yne (HC≡CCH2CH2CH2CH2CH2CH3) reacts rapidty with NaH, forming a gas that bubbles out of the reaction mixture, as one product. Oct-1-yne also reacts rapidty with CH3MgBr, and a different gas is produced. Write balanced equations for both reactions and identify the gases formed.arrow_forwardOptically pure Compound 1 undergoes a reaction at room temperature with sodium methoxide (NaOCH3) in methanol to form a single isomer of Compound 2 as shown below: 1. What are the stereochemical designations (R or S) of Compound 1 and Compound 2? 2. On the basis of the structure of Compound 2 and the information on the reaction conditions, suggest which type of mechanism Compound 1 undergoes . 3. The rate of the above reaction is determined experimentally to follow second-order kinetics. Give a fully labelled sketch of a reaction coordinate diagram for the reaction. 4. draw a mechanism on a piece of paper (using curly arrows) to show the formation of Compound 2 from Compound 1 including any activated complex. 5. If the sodium methoxide is left out of the reaction mixture, Compound 2 is formed in roughly equal amounts with another compound (Compound 3). Suggest a structure for Compound 3. With reference to the mechanism of the reaction and the structure of Compound 1, explain how these…arrow_forward
- Although diazomethane (CH2N2) is often not a useful reagent for preparing cyclopropanes, other diazo compounds give good yields of more complex cyclopropanes. Draw a stepwise mechanism for the conversion of diazo compound A to B, an intermediate in the synthesis of sirenin, the sperm attractant produced by the female gametes of the water mold Allomyces.arrow_forwardCompound F may be synthesised by the method below Compound A Compound F HCI CH3OH H₂SO4 Compound B CH3 CH₂ CH₂ CI Compound E NaOH K₂Cr₂O7 H₂SO4 Compound C K₂Cr₂O7 H₂SO4 Compound D Draw the structural formulas of compounds A, C, D, E and F in the boxes provided above.arrow_forwardAn unknown compound A of molecular formula C10H18O reacts with H2SO4 to form two compounds (B and C)of molecular formula C10H16. B and C both react with H2 in the presence of Pd-C to form decalin. Ozonolysis of B forms D, and ozonolysis of C forms a diketone E of molecular formula C10H16O2. Identify the structures of compounds A, B, C, and E.arrow_forward
