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 p-methylaniline (p-CH3C6H4NH2) istreated with following reagent. Part (b), then CH3COCl, AlCl3arrow_forwardDraw the organic products formed when attached allylic alcohol A is treated with following reagent. [1] PBr3; [2] LiAlH4; [3] H2Oarrow_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
