Reactions of Ethers
Ethers (R-O-R’) are compounds formed by replacing hydrogen atoms of an alcohol (R-OH compound) or a phenol (C6H5OH) by an aryl/ acyl group (functional group after removing single hydrogen from an aromatic ring). In this section, reaction, preparation and behavior of ethers are discussed in the context of organic chemistry.
Epoxides
Epoxides are a special class of cyclic ethers which are an important functional group in organic chemistry and generate reactive centers due to their unusual high reactivity. Due to their high reactivity, epoxides are considered to be toxic and mutagenic.
Williamson Ether Synthesis
An organic reaction in which an organohalide and a deprotonated alcohol forms ether is known as Williamson ether synthesis. Alexander Williamson developed the Williamson ether synthesis in 1850. The formation of ether in this synthesis is an SN2 reaction.
Which double bonds in the attached natural products can exhibitstereoisomerism? Nerolidol is isolated from the angel's trumpet plant,caryophyllene is present in hemp, and humulene comes from hops.
The stereoisomerism found around the double bond is called as geometrical isomerism. It is a feature of those compounds in which restricted rotation is present. Certain organic compounds which show geometrical isomerism are alkenes, cyanides, nitrides and certain cyclic compounds. The geometrical isomerism is found in those alkenes in which each vinyl carbon atom is bonded to different groups. One of the isomer that consists of the groups that possess the same priority on similar plane (either above or below the double bond) is called as cis-isomer and the isomer in which the groups that possess the same priority are present on the different side (one above and one below the double bond) is called as trans-isomer.
