Abstract:
Covering: up to 2020In this review, we present state of the art methods for performing dehydration reactions in alcohol substrates to deliver alkene products. The dehydration of alcohols typically proceeds through activation of the alcoholic moiety to a nucleofugal species followed by a subsequent elimination step. While the alcohol is a quintessential functional group, selective dehydration of alcohols in complex molecular scaffolds has not been harnessed to allow molecular diversification strategies. We present the perspective of utilizing complex molecular compounds containing alcoholic functionalities to generate novel molecular constructs that impose on chemical space of characterized bioactivity. Nature inspires the direct and selective dehydration of alcohols in complex molecules and demonstrates a potential that has not yet been realized by chemical methodology. We present challenging substrates for direct and selective dehydration reactions and argue that chemical methodology solving the challenges presented will be valued by synthetic and natural product chemists alike.

02:40Alkynes to Aldehydes and Ketones: Acid-Catalyzed Hydration
Analogous to alkenes, alkynes also undergo acid-catalyzed hydration. While the addition of water to an alkene gives an alcohol, hydration of alkynes produces different products such as aldehydes and ketones.
01:20Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
01:15Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
Synthesis of carbohydrates
Sugar molecules are covalently linked together by dehydration synthesis. During the reaction, the hydroxyl (-OH) group from...
01:15Hydrolysis
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...
