Suggest a synthesis of 1, using as starting materials the Her o CO,Et es -CHO 4. a) Lily aldehyde (1) is an ingredient used in perfumery. Suggest a synthesis of 1, using as starting materials, the ester 2 and 1-propanol. You may use any other applicable inorganic and/or organic reagents, but LiAIH, NaOH (aq). PCC, H2, DIBAL, and Pd/C are the most likely choices (depending on your synthetic route). No reaction mechanism(s) is required. Lily aldehyde b) Using 2-methyl-1,3-cyclopentanedione, acetaldehyde...
(b) For three of the following examples suggest reagents that would perform the following synthetic conversions (in each case more than one step may be required; you do NOT need to draw mechanisms) [3 x 3 OH (i) (in) NH2 (ii) Ph Ph CN (iv) Ph OH Ph NMe2 Draw mechanisms to explain the outcomes of the two following reactions (c) 2 x 3] Он MeMgBr Ph OEt 'Me Me Ph then H30* MeMgBr Ph NMe2 Ph Me then H3O
Suggest how you would carry out the following syntheses, showing all reagents necessary. More than one reaction may be involved.
The use of Grignard reagents in multi-step synthesis is widely employed. For each of the reaction sequences below, draw the major organic product that would be present after each reaction of the sequence. No mechanisms, no explanations, just draw the products (in total, 14 reaction products A to N are required). You may have to consult your lecture material and/or the textbook to solve some of these problems The use of Grignard reagents in multi-step synthesis is widely employed. For...
