(A) In the J → K transformation, dilute HCl (10%) was used to first deprotect/ unmask the acetal and ketal. Show the mechanism (use H³O*) for formation of the northern cyclohexene ring starting from the aldehyde and secondary amine. No need to show the mechanism of the acetal / ketal deprotection to the respective aldehyde and ketone. H -N-H CH3 CH3 CH3 CH3 N. OK
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.
