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.
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 ...
Solubility in water. 2 g/L Hazards GHS labelling: [1] ... 3 has been found to catalyze the reaction of N-sulfonyl oxaziridines with olefins to form 1,3-oxazolidine ...
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).
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]
These ligands were used in the hydrosilylation of ketones; achieving ee's of up to 93% [16] The first BOX ligands were reported a year later by Masamune et al. [13] and were first used in copper catalysed carbenoid cyclopropanation reactions; achieving ee's of up to 99% with 1% molar loadings. This was a remarkable result for the time and ...
The trucks were carrying about 25,000 liters of pesticides and 76 tons of sulfuric acid, according to the National Agency for Water and Basic Sanitation, raising concerns about environmental damage.
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.
