The reaction of 2-ethyl-1-pentene with Br2, with H2 + Pd/C, or with R2BH/THF followed by aqueous HO- + H2O2 leads to a racemic mixture. Explain why a racemic mixture is obtained in each case.
Unknown X, C5H9Br, does not react with bromine or with dilute KMnO4. Upon treatment with potassium tert-butoxide,X gives only one product, Y, C5H8. Unlike X, Y decolorizes bromine and changes KMnO4 from purple to brown.Catalytic hydrogenation of Y gives methylcyclobutane. Ozonolysis–reduction of Y gives dialdehyde Z, C5H8O2. Proposeconsistent structures for X, Y, and Z. Is there any aspect of the structure of X that is still unknown?
How can X be prepared from a constitutional isomer by a series of [2 + 2] cycloaddition reactions? Interest in molecules that contain several cyclobutane rings fused together has been fueled by the discovery of pentacycloanammoxic acid methyl ester, a lipid isolated from the membrane of organelles in the bacterium Candidatus Brocadia anammoxidans. Therole of this unusual natural product is as yet unknown.
Explain the following result. Although alkenes are generally more reactive than alkynes towards electrophiles, the reaction of Cl2 with but-2-yne can be stopped after one equivalent of Cl2 has been added.
Treatment of but-1-ene with hot KMno4/OH- gives product D, and subsequent acidification of the mixture gives product E. What are D and E. Give reaction equations.
Cembrene, C20H32, is a diterpenoid hydrocarbon isolated from pine resin. Cembrene has a UV absorption at 245 nm, but dihydrocembrene (C20H34), the product of hydrogenation with 1 equivalent of H2, has no UV absorption. On exhaustive hydrogenation, 4 equivalents of H2 react, and octahydrocembrene, C20H40, is produced. On ozonolysis of cembrene, followed by treatment of the ozonide with zinc, four carbonylcontaining products are obtained: Propose a structure for cembrene that is consistent with its formation from geranylgeranyl diphosphate.

Doxaprost, an orally active bronchodilator patterned after the natural prostaglandins , is synthesized in the following series of reactions starting with ethyl 2-oxocyclopentanecarboxylate. Except for the Nef reaction in Step 8, we have seen examples of all other types of reactions involved in this synthesis. Q. Assuming that the two side chains on the cyclopentanone ring are trans, how many stereoisomers are possible from this synthetic sequence?
