Concept explainers
Interpretation:
In 1HNMR, Disparlure, C19H38O, shows a large absorption in the alkane region, 1 to 2 δ and a triplet at 2.8 δ. Treatment of Disparlure first with aqueous acid and then with KMnO4 yielded undecanoic acid and 6-methylheptanoic acid. A structure for disparlure is to be proposed neglecting stereochemistry. Its structure also is to be given with stereochemistry if the actual compound is a chiral molecule with 7R, 8S stereochemistry.

- Propose a structural formula for compound A, C5H13N, given its IR and calculated 1H-NMR spectra.arrow_forwardAcid-catalyzed hydrolysis of HOCH2CH2C(CH3)2CN forms compound A (C6H10O2). A shows a strong peak in its IR spectrum at 1770 cm-1 and the following signals in its 1H NMR spectrum: 1.27 (singlet, 6 H), 2.12 (triplet, 2 H), and 4.26 (triplet, 2 H) ppm. Draw the structure for A and give a stepwise mechanism that accounts for its formation.arrow_forward19. A compound with molecular formula C6H12O2 exhibits two singlets in its 1H NMR spectrum, at d 1.4 (9H) and d 2.0 (3H). Its IR spectrum shows a strong absorption band near 1740 cm-1. What is the structure for this compound? Show the correlation of the spectra with the molecular structure.arrow_forward
- Compound I (C11H14O2) is insoluble in water, aqueous acid, and aqueous NaHCO3, but dissolves readily in 10% Na2CO3 and 10% NaOH. When these alkaline solutions are acidified with 10% HCl, compound I is recovered unchanged. Given this information and its 1H-NMR spectrum, deduce the structure of compound I.arrow_forwardAmines are converted into alkenes by a two-step process called Hofmann elimination. SN2 reaction of the amine with an excess of CH3I in the first step yields an intermediate that undergoes E2 reaction when treated with silver oxide as base. Pentylamine, for example, yields 1-pentene. Propose a structure for the intermediate, and explain why it readily undergoes elimination.arrow_forwardKetones undergo a reduction when treated with sodium borohydride, NaBH4. What is the structure of the compound produced by reaction of 2-butanone with NaBH4 if it has an IR absorption at 3400 cm-1 and M+=74 in the mass spectrum?arrow_forward
- A step in a synthesis of PGE1 (prostaglandin E1, alprostadil) is the reaction of a trisubstituted cyclohexene with bromine to form a bromolactone. Propose a mechanism for formation of this bromolactone and account for the observed stereochemistry of each substituent on the cyclohexane ring. Alprostadil is used as a temporary therapy for infants born with congenital heart defects that restrict pulmonary blood flow. It brings about dilation of the ductus arteriosus, which in turn increases blood flow in the lungs and blood oxygenation.arrow_forwardFollowing is a retrosynthetic analysis for an intermediate in the industrial synthesis of vitamin A. (a) Addition of one mole of HCl to isoprene gives 4-chloro-2-methyl-2-butene as the major product. Propose a mechanism for this addition and account for its regioselectivity. (b) Propose a synthesis of the vitamin A precursor from this allylic chloride and ethyl acetoacetate.arrow_forwardThree isomeric pentanols with unbranched carbon chains exist. Which of these isomers, upon dehydration at 180C, yields only 1-pentene as a product?arrow_forward
- Addition of m-xylene to the strongly acidic solvent HF/SbF5 at 45C gives a new species, which shows 1H-NMR resonances at 2.88 (3H), 3.00 (3H), 4.67 (2H), 7.93 (1H), 7.83 (1H), and 8.68 (1H). Assign a structure to the species giving this spectrum.arrow_forwardTerpin, prepared commercially by the acid-catalyzed hydration of limonene, is used medicinally as an expectorant for coughs. (a) Propose a structural formula for terpin and a mechanism for its formation. (b) How many cis, trans isomers are possible for the structural formula you propose?arrow_forward-Ocimene is a pleasant-smelling hydrocarbon found in the leaves of certain herbs. It has the molecular formula C10H16 and a UV absorption maximum at 232 nm. On hydrogenation with a palladium catalyst, 2,6-dimethyloctane is obtained. Ozonolysis of -ocimene, followed by treatment with zinc and acetic acid, produces the following four fragments: (a) How many double bonds does -ocimene have?
