4. The issue with enol/enolate syntheses is that a lot of the starting materials andproducts have the same functional groups (carbonyls). To determine whichenolate reaction is needed, thus, can depend on more than functional groupidentification: it sometimes depends on identifying how many carbons arebetween each carbonyl.So we're going to create a new synthetic map for carbon-carbon bond formationswith enols and enolates. Fill in the missing starting materials, reagents, orproducts as needed, and answer the given questions.a. The aldol, Option 1ai nipb.

It is often helpful to have more than one way to make a given molecule, as you may not know ahead of time which strategy will be more successful.... 4-Hexyne-2-ol can be made from propene in two different ways – one by way of a bromohydrin, using a protecting group strategy, and another by using an epoxide (which does not need a protecting group strategy). (a) First, give the synthesis which goes through the bromohydrin and uses a protecting group. OH (b) Now, modify the synthesis (you may start with propene, or any other molecule you already made in part (a)) to accomplish the synthesis of 4-hexyne-2-ol using an epoxide.

Epoxides are highly strained and can alleviate the strain by reacting under acidic and basic conditions to give different regiochemical and stereochemical products. In this epoxide tutorial, we will cover 1. ring opening of unsubstituted epoxide 2. which nucleophiles will open an epoxide 3. regiochemical and stereochemical results of basic ring opening of asymmetrical epoxides 4. regiochemical and stereochemical results of acidic ring opening Step 1: In a simple unsubstituted epoxide, a nucleophile can attack the epoxide and open the ring to give an alcohol after aqueous workup. HO: -:Nuc 2. H₂O Nuc Common nucleophiles that will undergo this reaction include alkoxides, nitriles, thiols, carbanions, acetylides, Grignard reagents and lithium aluminum hydride.
