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.
While investigating reactions of bromoethylamine hydrobromide, he treated it with silver carbonate and isolated a product with melting point around 90–91°C. He determined its empirical formula correctly, but neither gave it a specific name not studied its properties. [4]
2‑oxazoline, 3‑oxazoline, and 4‑oxazoline (from left to right) Three structural isomers of oxazoline are possible depending on the location of the double bond, however only 2‑oxazolines are common. 4‑Oxazolines are formed as intermediates during the production of certain azomethine ylides [2] but are otherwise rare. 3‑Oxazolines are even less common but have been synthesised ...
Various oxidation reactions. One study [ 7 ] reports on the oxidation of 4,5-diphenyloxazole with 3 equivalents of CAN to the corresponding imide and benzoic acid : In the balanced half-reaction three equivalents of water are consumed for each equivalent of oxazoline, generating 4 protons and 4 electrons (the latter derived from Ce IV ).
2-Oxazolidinone is the parent compound of several protein synthesis inhibitor antibiotics and the Evans chiral auxiliaries for aldol reactions. Cycloserine is an antibiotic based on the 3-isoxazolidone parent.
DEA is a chemical feedstock used in the production of morpholine. [3] [4] Amides derived from DEA and fatty acids, known as diethanolamides, are amphiphilic. The reaction of 2-chloro-4,5-diphenyloxazole with DEA gave rise to ditazole. The reaction of DEA and isobutyraldehyde with water removed produces an oxazolidine. [6] [7]
Thiazolidine is a heterocyclic organic compound with the formula (CH2)3(NH)S. It is a 5-membered saturated ring with a thioether group and an amine group in the 1 and 3 positions. It is a sulfur analog of oxazolidine. Thiazolidine is a colorless liquid.
Isoxazolidine is the organic compound with the formula (CH 2) 3 (NH)O. It is the parent of a family of compounds called Isoxazolidines, which are saturated C 3 NO heterocyclic rings where the nitrogen and oxygen occupy adjacent positions (1 and 2).
