In this part we will provide conclusive proof of the stereochemistry of the product by preparing the acetonide of hydrobenzoin and examining its 'H NMR spectrum. An acetonide is a cyclic ketal prepared from acetone and either a 1,2- or a 1,3-diol. Our procedure uses anhydrous ferric chloride as a Lewis acid catalyst for the preparation of the acetonide.

The base-promoted rearrangement of an -haloketone to a carboxylic acid, known as the Favorskii rearrangement, is illustrated by the conversion of 2-chlorocyclohexanone to cyclopentanecarboxylic acid. It is proposed that NaOH first converts the a-haloketone to the substituted cyclopropanone shown in brackets and then to the sodium salt of cyclopentanecarboxylic acid. (a) Propose a mechanism for base-promoted conversion of 2-chlorocyclohexanone to the proposed intermediate. (b) Propose a mechanism for base-promoted conversion of the proposed intermediate to sodium cyclopentanecarboxylate.
Predict the products of the reactions of the following compounds with: (1) chromic acid or excess sodium hypochlorite with acetic acid. (2) PCC or NaOCl (1 equivalent) with TEMPO. (a) cyclohexanol (b) 1-methylcyclohexanol(c) cyclopentylmethanol (d) cyclohexanone

The p-toluenesulfonate derived from (R)-2-octanol and p-toluenesulfonyl chloride was allowed to react with sodium benzenethiolate (C6H5SNa). Give the structure, including stereochemistry and the appropriate R or S descriptor, of the product.
Reaction of p-cresol with two equivalents of 2-methylprop-1-ene affords BHT, a preservative with molecular formula C15H24O. BHT gives the following 1H NMR spectral data: 1.4 (singlet, 18 H), 2.27 (singlet, 3 H), 5.0 (singlet, 1 H), and 7.0 (singlet, 2 H) ppm. What is the structure of BHT? Draw a stepwise mechanism illustrating how it is formed.
Compelling evidence for the existence of a tetrahedral intermediate innucleophilic acyl substitution was obtained in a series of elegantexperiments carried out by Myron Bender in 1951. The key experimentwas the reaction of aqueous −OH with ethyl benzoate (C6H5COOCH2CH3)labeled at the carbonyl oxygen with 18O. Bender did not allow thehydrolysis to go to completion, and then examined the presence of alabel in the recovered starting material. He found that some of therecovered ethyl benzoate no longer contained a label at the carbonyloxygen. With reference to the accepted mechanism of nucleophilic acyl substitution, explain how this provides evidence for a tetrahedralintermediate.
B-Damascenone belongs to a family of fragrant natural products called rose ketones that have been used in the perfume industry. In one synthesis of B-damascenone, the reaction of compound 1 with one equivalent of MCPBA afforded two constitutionally isomeric epoxides (compounds 2 and 3), which were then converted into diol 4 upon subsequent treatment with aqueous acid. Identify the structures of epoxides 2 and 3, and propose a mechanism that converts each of them into compound 4 in the presence of H30+. OCH, OH OCH, МСВРА 2 +3 (one equiv.) OH B-Damascenone
Following 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.
Following is a synthesis for toremifene, a nonsteroidal estrogen antagonist whose structure is closely related to that of tamoxifen. (a) This synthesis makes use of two blocking groups, the benzyl (Bn) group and the tetrahydropyranyl (THP) group. Draw a structural formula of each group and describe the experimental conditions under which it is attached and removed. (b) Discuss the chemical logic behind the use of each blocking group in this synthesis. (c) Propose a mechanism for the conversion of D to E. (d) Propose a mechanism for the conversion of F to toremifene. (e) Is toremifene chiral? If so, which of the possible stereoisomers are formed in this synthesis?
Following is a retrosynthetic analysis for the synthesis of the herbicide (S)-Metolachlor from 2-ethyl-6-methylaniline, chloroacetic acid, acetone, and methanol. Show reagents and experimental conditions for the synthesis of Metolachlor from these four organic starting materials. Your synthesis will most likely give a racemic mixture. The chiral catalyst used by Novartis for reduction in Step 2 gives 80% enantiomeric excess of the S enantiomer.
What product would you expect from reaction of one equivalent of methanol with a cyclic anhydride, such as phthalic anhydride (1,2-benzenedicarboxylic anhydride)? What is the fate of the second half of the anhydride?
