Hi
I need some help with this synthesis please!
Homework Answers
Explanation: Hydroxide ion is a strong base which abstracts the most acidic proton and eliminates leaving group to form a doube bond. Now, [3,3]-sigmatropic reaarangement gives the carbonyl group on benzene ring. Now elimination of proton regenerates aromaticity.

(a) Propose a one-step mechanism using curved arrow notation for the formation of styrene oxide from styrene using MCPBA, as shown below. (b) Propose a step-wise mechanism using curved arrow notation for reaction of styrene oxide with (CH_3)_2 CHNH_2 that includes the structure of the expected product. To simplify the mechanism, do not show formation of enantiomers.

9 10-Synthesis question. Show how the starting material can be converted to the product through any of the reactions you have learned in Ochem-l and Ochem-II. Show all the reagents you need and indicate the stereochemistry when appropriate. You do not need to show arrow pushing like in a mechanism question, only the reactions. If a chiral molecule is formed mark the chiral center with an asterisk (*) and write "racemic" below the structure. All carbon...
