And so we're going to need to do the reactions that we did in the previous synthesis in a different order here. So we could do a nitration to put the nitro group on, and we could do a Friedel-Crafts acylation to put this acyl group on our ring. Check Also: - Carboxylic Acids and Their Derivatives Practice Problems. And then, finally, we have two meta directors, which we now brominate, which would direct the bromine to the final position.

In this case it should be apparent that cyclohexanol may be substituted for cyclohexanone, since the latter could then be made by a simple oxidation. This refers to substitutes on the starting material and in this case benzene with the Br attached is acceptable because Br is not a powerful electron withdraw group. However, one or more of the reactants is larger than C4 and must therefore be prepared independently before use.

First, it should be recognized that the amine group is best introduced at the end of the synthesis, by reacting ethylamine with an ester (or acyl chloride derivative) of spiro[3. And so our goal is to make this molecule from benzene. So next we just have to remember how to put a bromine on a benzene ring, and of course it's a bromination reaction. For example, bromination of nitrobenzene gives an 80% yield of m-bromonitrobenzene. Each simpler structure, so generated, becomes the starting point for further disconnections, leading to a branched set of interrelated intermediates. We are asked to tell about these 4 reagents, which are causing this conversion of benzine to epoxide.
