(4) Propose a synthesis of the target molecule from the indicated starting materials. Cau- tion! Long, inefficient syntheses are penalized. & NH (a) [12 points) (b) [12 points) 2 Ph Ph Ph сн. acetophenone All of the carbons in the target must come from acetophenone.
(3) Propose an efficient synthesis of target molecules (a) and (b). All of the carbons in the targets must come from one of the compounds below. Draw the structure of the product formed after each synthetic step. Do not write mechanisms.

Provide multistep synthesis for the following target molecule from the indicated starting materials NH2 from 0 from NO2 Br
1. Propose a synthesis for either of the following molecules using the indicated starting materials. You don't have to use all of them, but all your carbon atoms must come from them alone. (Hint: A five membered lactone will spontaneously form from the correct hydroxy acid.) If you provide syntheses for both a 10 pt bonus will be awarded. OH со, КCN Br н Н NO, Br NH2 2. Propose a mechanism to account for the following reaction. Used the...
