- Treatment of -D-glucose with methanol in the presence of an acid catalyst converts it into a mixture of two compounds called methyl glucosides (Section 25.3A). In these representations, the six-membered rings are drawn as planar hexagons. (a) Propose a mechanism for this conversion and account for the fact that only the OH on carbon 1 is transformed into an OCH3 group. (b) Draw the more stable chair conformation for each product. (c) Which of the two products has the chair conformation of greater stability? Explain.Rank the following groups in order of decreasing priority. −C≡CH, −CH(CH3)2, −CH2CH3, −CH=CH2Ee.2. How do you draw the S enantiomer of 1-methylcyclohex-2-ene-1-carboxylic acid?
- The chiral catalyst (R)-BINAP-Ru is used to hydrogenate alkenes to give alkanes . The products are produced with high enantiomeric excess. An example is the formation of (S)-naproxen, a pain reliever. Q.How can one enantiomer of naproxen be formed in such high yield?What stereoisomers are formed in the following reaction? Are they enantiomers or diastereomers? Which stereoisomer is formed in greater yield?a. With attention to stereochemistry, indicate the product of the SN2 reaction of cis-1-bromo-2methylcyclohexane. b. Draw and identify (R) and (S) enantiomers of lactic acid, CH3CH(OH)COOH. Use the proper conventions to draw Fischer projections.
