- The Meerwein-Ponndorf-Verley reaction involves reduction of a ketone by treatment with an excess of aluminum triisopropoxide, [(CH3)2CHO]3Al. The mechanism of the process is closely related to the Cannizzaro reaction in that a hydride ion acts as a leaving group. Propose a mechanism.arrow_forwardTreatment of 1-aminoadamantane, C10H17N, with methyl 2,4-dibromobutanoate in the presence of a nonnucleophilic base, R3N, involves two successive SN2 reactions and gives compound A. Propose a structural formula for compound A.arrow_forwardWhen cis-2-decalone is dissolved in ether containing a trace of HCl, an equilibrium is established with trans-2-decalone. The latter ketone predominates in the equilibrium mixture. Propose a mechanism for this isomerization and account for the fact that the trans isomer predominates at equilibrium.arrow_forward
- Treatment of an aldehyde or ketone with cyanide ion (-:C=N), followed by protonation of the tetrahedral alkoxide ion intermediate, gives a cyanohydrin. Show the structure of the cyanohydrin obtained from cyclohexanone.arrow_forwardA 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_forwardAcid-catalyzed hydrolysis of the following epoxide gives a trans diol. Of the two possible trans diols, only one is formed. How do you account for this stereoselectivity?arrow_forward
- -Hydroxyketones and -hydroxyaldehydes are also oxidized by treatment with periodic acid. It is not the -hydroxyketone or aldehyde, however, that undergoes reaction with periodic acid, but the hydrate formed by addition of water to the carbonyl group of the -hydroxyketone or aldehyde. Write a mechanism for the oxidation of this -hydroxyaldehyde by HIO4.arrow_forwardEthylene oxide is the starting material for the synthesis of 1,4-dioxane.
