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.
In the Cornforth rearrangement of 4-acyloxazoles is a thermal rearrangement reaction with the organic acyl residue and the C5 substituent changing positions. 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 :
[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 ...
2-phenyl-3-methyl-4-ethylmorpholine (phenmetetrazine) 92196-09-3 2-phenyl-3,5-dimethylmorpholine : 1218345-44-8 2-phenyl-3,6-dimethylmorpholine (6-methylphenmetrazine, 3,6-DMPM) 92902-99-3 2-phenyl-5,5-dimethylmorpholine : 42013-48-9 2-phenyl-3-methylmorpholin-5-one (fenmetramide) 5588-29-4 4-isopropyl-2-phenylmorpholine [5] 23222-62-0
3,4-Methylenedioxyphenylpropan-2-one [1] or piperonyl methyl ketone (MDP2P or PMK) is a chemical compound consisting of a phenylacetone moiety substituted with a methylenedioxy functional group. It is commonly synthesized from either safrole (which, for comparison, is 3-[3,4-(methylenedioxy)phenyl]-2-propene) or its isomer isosafrole via ...
The diazo group (N 2) can be replaced by many other groups, usually anions, giving a variety of substituted phenyl derivatives: . C 6 H 5 N 2 + + Nu − → C 6 H 5 Nu + N 2. These transformations are associated with many named reactions including the Schiemann reaction, Sandmeyer reaction, and Gomberg-Bachmann reaction.
3,4-Di methoxy phenethylamine (DMPEA) is a chemical compound of the phenethylamine class. It is an analogue of the major human neurotransmitter dopamine where the 3- and 4-position hydroxy groups have been replaced with methoxy groups. It is also closely related to mescaline which is 3,4,5-trimethoxyphenethylamine and to 3,4 ...
