Reactions at the Alpha Carbon Atom

The position next to the ketone or aldehyde functional group is termed as alpha position and the reaction which occurs at alpha position is called alpha substitution reaction. In an alpha substitution reaction, the alpha proton atom is substituted by an electrophile by the formation of an enol intermediate or enolate ion intermediate. Most of the carbonyl compounds go through an alpha substitution reaction.

2-Pentylcinnamaldehyde, commonly called flosal, is a perfume ingredient with a jasmine-like odor. Flosal is an α,β-unsaturated aldehyde made by a crossed aldol reaction between benzaldehyde (C6H5CHO) and heptanal (CH3CH2CH2CH2CH2CH2CHO), followed by dehydration. Draw a stepwise mechanism for the following reaction that prepares flosal.
The anticoagulant Warfarin can be synthesized by a conjugate addition (Michael addition) reaction as shown below: a) Propose a mechanism for the reaction starting from the enolate shown below. You can assume water is present for any proton transfers needed.b) We saw that the keto tautomer is normally preferred over the enol tautomer, however, the enol tautomer is present in the final product (Warfarin) and that is the more stable tautomer in this case. Why do you think the enol tautomer is more stable? Hint: consider the molecule as a whole.
