Draw a mechanism for each of the three steps in the preparation of the 6-ethoxycarbonyl-3,5-diphenyl-2-cyc lohexenone. you may assume that sodium hydroxide functions as a base and ethanol serves as a proton source.

The mechanism of the reaction is as follows:

The first step is the supplementation of the acetate and the chalcone under basic conditions. The reaction is mentioned in the attachment.

The second step incorporates the reaction of the product from the first step to produce a cyclic product. This reaction goes through the Aldol mechanism. The reaction is mentioned in the attachment below.

Finally, the outcome produced in the above reaction goes through dehydration to produce a desired outcome. The reaction is mentioned in the attachment below.
