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.
[4] Nine years later Gabriel returned to the topic together with G. Eschenbach, developing a more efficient synthesis using sodium bicarbonate instead of the silver salt. They referred to the compound as "Oxäthylcarbaminsäureanhydrid" (hydroxyethylcarbamic acid anhydride), recognizing its relationship to ethanolamine and its cyclic structure.
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 ...
This is a static list of 599 additives that could be added to tobacco cigarettes in 1994. The ABC News program Day One first released the list to the public on March 7, 1994. [1]
This is a list of aminorex analogues. Aminorex itself is a stimulant drug with a 5-phenyl-2-amino-oxazoline structure. It was developed in the 1960s as an anorectic, [1] [2] [3] but withdrawn from sale after it was discovered that extended use produced pulmonary hypertension, often followed by heart failure, which resulted in a number of deaths.

The oxazolidones and isoxazolidones are a set of six isomeric five-membered heterocyclic compounds consisting of a carbonyl group, an oxygen atom, a nitrogen atom with a hydrogen atom attached, and two methylene groups.
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).
G-130 (GP-130, 2-Phenyl-5,5-dimethyltetrahydro-1,4-oxazine) [1] is a drug with stimulant and anorectic effects, related to phenmetrazine. [ 2 ] [ 3 ] [ 4 ] Structural analogs
