propose a retrosynthesis, and a way in which this diene can be synthesized

Complete the following reactions, clearly indicating regio-and stereochemistry where applicable. In cases, where ortho-and para-products are formed, draw both.

10) Using the carbon-containing starting material(s), propose a synthesis the following retrosynthesis scheme. Provide structures for all intermediates. The carbon atoms in the product must originate from the starting material(s), but you may use as many equivalents of each starting material as you would like, and any reagent/reaction you know. (note: no mechanisms are required). E

(d) Using A, design a two-step synthesis of B that makes use of a pericyclic reaction. Your answer should name the pericyclic reaction involved and include a reaction mechanism for each step. OH Ph Ph. CO,Me OH A

Carry out the following synthesis, using any necessary reagents. Show any synthetic intermediates. Mechanisms do not need to be shown. O₂N. CI

Provide an arrow pushing mechanism for the following transformation. Draw out a representation of the transition-state in the rate-determining step.
