The flowchart of reaction chain and the stereochemical formulas for A, B, C and D are to be proposed and the reactions involved in the transformations are to be outlined. Concept introduction: Addition of hydrogen halides is by anti-addition mechanism, which produces structural isomers. Oxidation of alkenes with ozone, in the presence of dimethyl sulphate, results in the formation of ketones or aldehydes depending on the orientation and position of the double bond. Two carbonyl groups form in place of one double bond present in the alkene Potassium tert-butoxide (t-BuOK) is a bulky reagent. It reacts with alkyl halides to form alkenes by elimination mechanism. Potassium tert-butoxide is very sensitive towards steric interactions.

Compound J, C16H16Br2, is optically active. On treatment with strong base, compounds K and L (each C16H14) are formed; K and L each absorb only 2 equivalents of hydrogen when reduced over a Pd/C catalyst. Compound K reacts with ozone to give phenylacetic acid (C6H5CH2COOH), while similar treatment of L gives 2 products. One product, M, is an aldehyde with formula C7H6O; the other product is glyoxal (CHO)2. Draw the structure of compound L.

Deduce the structures of compounds A and B, two of the major components of jasmine oil, from the given data. Compound A: C9H10O2; IR absorptions at 3091–2895 and 1743 cm-1; 1H NMR signals at 2.06 (singlet, 3 H), 5.08 (singlet, 2 H), and 7.33 (broad singlet, 5 H) ppm. Compound B: C14H12O2; IR absorptions at 3091–2953 and 1718 cm-1; 1H NMR signals at 5.35 (singlet, 2 H) and 7.26–8.15 (multiplets, 10 H) ppm.

Spirocyclic compounds, such as compound 3, are made and used by insects for the purposes of communication. The first step of a synthesis of compound 3 involves treatment of (S)-1,2-epoxypropane (compound 1) with lithium acetylide, followed by acid workup, to give compound 2, as shown below (J. Org. Chem. 2005, 70, 3054-3065). Identify the structure of compound 2 and provide a mechanism for its formation. (Hint: The carbon-lithium bond reacts in a way that is similar to the carbon-magnesium bond of a Grignard reagent.) 1 13.17 a 1) Li—= 2) H₂O+ нас!!!!!!
