Oxazolidines are five-membered ring compounds consisting of three carbons, nitrogen and oxygen. Oxygen and nitrogen are in the 1 and 3 positions, respectively. Oxazolidine is in general yellow or slightly yellow, alkaline liquid or solid, easily hydrolyzed by water or alcohol. It is insoluble in water (or hydrolyzed); soluble in benzene and chloroform. Oxazolidine derivatives are five-membered cyclic compounds containing at least one oxygen and nitrogen in their molecular structure. Oxazolidine derivatives are known to possess various therapeutic activities, such as anticancer and antibiotic properties.
Benzene is an important organic compound with the chemical formula C6H6, and its molecule consists of a ring of 6 carbon atoms, each with 1 hydrogen atom. Benzene is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity at room temperature, and has a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing one hydrogen atom from the benzene ring is called phenyl. Benzene is one of the most important basic organic chemical raw materials. Many important chemical intermediates can be derived from benzene through substitution reaction, addition reaction and benzene ring cleavage reaction.
