Generally, amides can be hydrolyzed in either acidic or basic solution. The mechanisms are much like those of ester hydrolysis (Section A), but the reactions are very much slower, a property of great biological importance (which we will discuss later): As we have indicated in Section , amide hydrolysis can be an important route to amines. Hydrolysis under acidic conditions requires strong acids . Dioxolane is a heterocyclic acetal with the chemical formula (CH 2) 2 O 2 CH is related to tetrahydrofuran by interchange of one oxygen for a CH 2 group.
