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). NO2 Br + он

parts a, b, c, d, e, and f

Propose a sequence of reactions to prepare the specified target compound from the indicated starting materials.  All of the carbon atoms in the target must originate in the specified starting materials.  Keeping this restriction in mind, you may use any other organic or inorganic reagents necessary to complete the synthesis. It is only necessary to show the overall transformations involved in your proposed synthesis.

4) Give the synthesis for the following compounds. Mechanism is not required. All reagents must be what we have covered in class up to now. A) B) OH НО. H ol COOH

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

Propose a retrosynthetic analysis of benzocaine from the starting material shown. Your answer should include both the synthons and the reagents that would be employed in the actual synthesis. H2N

Propose syntheses for the product shown on the left starting from the indicated compound (shown on the right). Your answer should include a retrosynthetic analysis and a proposed synthetic route with reagents.
