  2. Oxazolidine - Wikipedia

    en.wikipedia.org/wiki/Oxazolidine

    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. Oxazolines are unsaturated analogues ...

    en.wikipedia.org/wiki/3,5-Dimethylpyrazole

    3,5-Dimethylpyrazole is an organic compound with the formula (CH 3 C) 2 CHN 2 H. It is one of several isomeric derivatives of pyrazole that contain two methyl substituents. The compound is unsymmetrical but the corresponding conjugate acid (pyrazolium) and conjugate base (pyrazolide) have C 2v symmetry. It is a white solid that dissolves well ...

    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 :

  6. 2-Oxazolidinone - Wikipedia

    en.wikipedia.org/wiki/2-oxazolidinone

    [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.

  7. 3,4-Dimethoxyphenethylamine - Wikipedia

    en.wikipedia.org/wiki/3,4-Dimethoxyphenethylamine

    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 ...
