4. The issue with enol/enolate syntheses is that a lot of the starting materials and products have the same functional groups (carbonyls). To determine which enolate reaction is needed, thus, can depend on more than functional group identification: it sometimes depends on identifying how many carbons are between each carbonyl. So we're going to create a new synthetic map for carbon-carbon bond formations with enols and enolates. Fill in the missing starting materials, reagents, or products as needed, and answer the given questions. a. The aldol, Option 1 ai nip b. The aldol, Option 2 R3 R R3 R² What kind of functional group is this product? · R3 c. The Claisen Condensation R3 OH R¹ R2 Circle the correct answer: The alcohol is (alpha/beta) to the carbonyl. base · + R² OR3 R1 R1 and R2 alkyl, aryl, OR R² Fill in the answer: The product is a (1, ) dicarbonyl

2. Complete the following six reaction sequences. In the boxes provided draw the intermediate product needed to complete the reaction sequence. In addition, above the arrow for each reaction draw (or write) the reagents necessary for the chemical transformations. More than one reaction might be needed for each arrow. Consider stereochemistry where necessary. Use reactions only from CHEM2401 or CHEM2402. Mechanisms are not required. d. ? e. ? f. ? ? ? ? ? би NH2 ? ? OH
4) When a mixture of two different compounds both containing a hydrogens are placed under acidic or basic conditions, crossed aldol products can be formed. By either self-condensation or cross condensations. Draw the 4 aldol and 4 a.B-unsaturated ketones that can be made from the following mixed system. -OH 4 products One way to control this is by either having only one compound with a hydrogens or by reacting the desired nucleophile with lithium diisopropylamide (LDA) before addition of second carbonyl. The issue here is that this reaction stops at the aldol unless excess base is used. он LDA OH heat Show a synthetic scheme of how to use the following carbonyls to control the formation of each cross product (i.e. each as nucleophile and electrophile, two reactions). and

I am a bit confused regarding this mechanism. Is it the R' that is attacking the carbon, or the bond that is attacking the partially positive carbon? Also, how does MgX end up eventually separating? Is it just because of the repelling positive charge with the alkoxide?
