(a)
Interpretation:
The synthesis of given tertiary
Concept introduction:
Reductive amination is also known as reductive alkylation. This is basically used for the conversion of a carbonyl group to an amine via an intermediate imine. The carbonyl groups generally are
(b)
Interpretation:
The synthesis of given tertiary amine in three different ways by using acylation-reduction is to be shown.
Concept introduction:
Acylation-reduction is a process in which compound first undergoes acylation process. One of the best acylation processes is Friedel Craft acylation. Then the compound undergoes reduction process by suitable reducing agent or by catalytic reduction in the presence of metals like

- Which reaction intermediate (A or B) is more likely to form in the epoxide ring opening reaction? Reactions prefer to react through lower energy intermediates. Hint: how might you justify one structure being lower in energy than the other? Draw structures as part of your explanation why. F F. BOH F :0. Br Br Br H H epoxide ring opening Structure A Which alcohol structure shown below would be less acidic? Explain why. OH Structure B : 0. : OHarrow_forwardComplete part 2 of the question (I already did part 1) as explained in the image.arrow_forward2. When the following pair of reactants are combined in the presence of a basic catalyst, a number of aldol addition products are possible (since both of the reactants possess an acidic alpha proton). a. b. C. CH3 + H₂C H NaOH/H₂O Draw the structures for the two possible enolate ions. Draw the structures for all possible aldol addition products (also show the enolate ion and electrophilic carbonyl compound responsible for each product). For each of the aldol addition products predicted in part b, draw the structures for all of the corresponding aldol condensation products after loss of water (if E/Z isomers are possible, show both isomers)arrow_forward
- 1. For the following reaction step, indicate which pattern of arrow pushing it represents. a. proton transferb. rearrangementc. loss of a leaving group2. Melphalan, a drug used in chemotherapy, reacts with itself in the body before binding with its target, as illustrated in the mechanism below. What is the first pattern of arrow pushing seen in this reaction? a. rearrangementb. loss of a leaving groupc. nucleophilic attackarrow_forwardWhich of the following does not support a nucleophilic attack of a covalent catalysis? a. Hydroxyl b. Sulfhydryl c. Imidazole d. Amino e. Methylarrow_forwardPropose an efficient synthesisarrow_forward

Show reaction mechanism.arrow_forwardDevise a synthesis of each biologically active compound from benzene.arrow_forwardExplain the synthesis of B-ionone. Also do the mechanism with explanation in detailsarrow_forward
- 4. Draw the proper products for the following acid/base reaction, with diisopropylamide (1) acting as a base, and cyclohexanone (II) acting as an acid in the forward direction. IIarrow_forwardCyclohexanone reacts with hydroxylamine hydrochloride (NH2OH HCl) to give the oxime product, which upon reaction with sulfuric acid gives the 7-member cyclic amide called caprolactam as the major product. a. Draw both of these reactions. b. Draw mechanisms that account for the formation of the oxime and the cyclic amide. For full credit, you must use the curved arrow notation to show all bond making and bond breaking. You must also show all reactive intermediates.arrow_forward(b) Draw a stepwise mechanism for the following transformation from A to B. This reaction is one of the key steps in a synthesis of lysergic acid diethyl amide (aka LSD). CI A CH ₂ AIC13 B CH₂ several steps away from lysergic acid diethyl amide (LSD)arrow_forward
