2-Oxazolidinone is a heterocyclic organic compound containing both nitrogen and oxygen in a 5-membered ring. ... -3-phenylurea upon treatment with aniline ...
Oxazolidine is a five-membered heterocycle ringwith the formula (CH 2) 3 (NH)O.The O atom and NH groups are not mutually bonded, in contrast to isoxazolidine. [ 2 ] [ 3 ] Oxazolidines (emphasis on plural) are derivatives of the parent oxazolidine owing to the presence of substituents on carbon and/or nitrogen.
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). [1] Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles .
