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.
The compound arises by the reaction of an ethanolamine and dimethylcarbonate [1] or related phosgene equivalents. [2] It is one of waste products generated in amine gas treating due to cyclization of ethanolamine carbamate. [3]
Two conceptually different approaches are feasible for preparing oxazolidine- and thiazolidine-ring-containing dipeptide derivatives: (1) the in situ acylation of Ser- or Thr-derived oxazolidines or Cys-derived thiazolidines using acid fluorides or N-carboxyanhydrides (NCA); and (2) the direct insertion of the oxazolidine systems into ...
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 ...
