Unformatted text preview: are required to produce each of the following in one step . (where H + or HO-workup does not constitute a step) a. b. c. COOH d. OH O O 7. Using benzaldehyde as a starting material and reagents that provide no more than 1 carbon to the final product show synthesis of the following: CHO 8. Propose reasonable syntheses for the following: O OH O 9. Draw the structure of the product of each of the following reactions: CHO + P(C 6 H 5 ) 3 + O Ph 3 P=CHC 6 H 5 O + Ph 3 P=CH 2 10*. For the brave: Enamines are very useful intermediates that are used to alkylate ketones and aldehydes. Here is an example of the synthesis using enamine. Attempt reasonable mechanisms for all the steps: O N H O cat. H + N O Br N O H + /H 2 O O...
