  ORGANIC CHEMISTRY  LL PRINT UPGRADE, Chapter 13, Problem 72IP

Concept Introduction:

In the acid-catalyzed ring-opening of an epoxide with water, first proton transfer takes place and then nucleophilic attack takes place via the SN2 mechanism. In the end, proton transfer step takes place that removes the charge formed after the attack of the neutral nucleophile on a more substituted position. Similarly, ring opening of epoxide can also take place in a basic medium. This results in an attack of the nucleophile on a less substituted position.

Grignard reagent is a versatile tool in synthetic organic chemistry. Using bromocyclopentane as a starting material, show how a Grignard reagent, X, is synthesized. Reaction of X with water produces compound Y while treatment in carbon dioxide followed by hydrolysis forms compound Z. 3-methyl-2butanone reacts with X and hydrolyses to yield compound AA. Draw the structural formulae of compounds Y, Z and AA and write the chemical equations respectively.
3. Isoerythrogenic acid, C18H26O2, is an acetylenic fatty acid that turns a vivid blue on exposure to UV light. On Catalytic hydrogenation over a palladium catalyst, five molar equivalents of hydrogen are absorbed, and stearic acid, CH3(CH2)16CO2H, is produced. Ozonolysis of isoerythrogenic acid yields the following products: formaldehyde, CH2O, malonic acid, HO2CCH2CO2H, adipic acid, HO2C(CH2)4CO2H, and the aldehyde carboxylic acid, OHC(CH2)6CO2H. Provide a structure for isoerythrogenic acid.
Treatment of anthranilic acid with nitrous acid gives an intermediate, A, that contains a diazonium ion and a carboxylate group. When this intermediate is heated in the pres- ence of furan, a tricyclic compound is formed. Propose a structural formula for com- pound A and a mechanism for the formation of the tricyclic product. COOH NANO, HCI + CO, + N2 NH2 Anthranilic acid
