Concept Introduction: Aldol reaction is the condensation reaction of the
The aldol reaction that takes place within the same molecule in the presence of strong base is known as intramolecular aldol reactions. This reaction generally takes place within the dicarbonyl compounds in which one carbonyl group forms the enolate ion that acts as a nucleophile and the carbonyl carbon of the second carbonyl group acts as an electrophile.

- Draw the products formed when each compound is treated with HNO3 and H2SO4.State whether the reaction occurs faster or slower than a similar reaction with benzene.arrow_forwardDraw the products formed (including stereoisomers) when each compound is reduced with NaBH4 in CH3OH.arrow_forwardDraw reaction mechanisms with all reactants, arrows, intermediates, and products. Your mechanism must account for all the products if more than one product is formed. 4-methycyclohexanol with phosphoric acid H3PO4 to for 1-methycyclohexene, 3- methylcyclohexene and 4-methycyclohexenearrow_forward

A) Keto-enol isomerism B) Keto-enol tater tot-ism C) Keto-enol conversion D) Keto-enol tautomerismarrow_forwardWhy can’t 1-methylcyclohexanol be prepared from a carbonyl compound by reduction?arrow_forwardWhat steps are needed to convert benzene into p-isobutylacetophenone, a synthetic intermediate used in the synthesis of the anti-inammatory agent ibuprofen.arrow_forward
- What steps are needed to convert benzene into p-isobutylacetophenone, a synthetic intermediate used in the synthesis of the anti-infl ammatory agent ibuprofen.arrow_forward(a) Draw the products (including stereoisomers) formed when 2methylhex-2-ene is treated with HBr in the presence of peroxides. (b) Draw the products (including stereoisomers) formed when (S)-2,4dimethylhex-2-ene is treated with HBr and peroxides under similar conditions.arrow_forward2-Pentylcinnamaldehyde, commonly called flosal, is a perfume ingredient with a jasmine-like odor. Flosal is an a,B-unsaturated aldehyde made by a crossed aldol reaction between benzaldehyde (CsH;CHO) and heptanal (CH,CH,CH2CH,CH,CH2CHO), followed by dehydration. Draw a stepwise mechanism for the following reaction that prepares flosal. CHO OH CgH;CHO CHO + Hо H20 flosal (perfume component)arrow_forward
