Why can’t 1-methylcyclohexanol be prepared from a carbonyl compound by reduction?

What steps are needed to convert benzene into p-isobutylacetophenone, a synthetic intermediate used in the synthesis of the anti-inammatory agent ibuprofen.

Identify the best reagents to complete the following reaction. HO, CI

Draw 3-methylcyclohex-2-enone

2-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)
