So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Banno, Taisuke; Kawada, Kazuo; Matsumura, Shuichi researched the compound: (S)-1-(Dimethylamino)propan-2-ol( cas:53636-17-2 ).Safety of (S)-1-(Dimethylamino)propan-2-ol.They published the article 《Chemo-enzymatic synthesis and properties of novel optically active cationics containing carbonate linkages》 about this compound( cas:53636-17-2 ) in Journal of Oleo Science. Keywords: carbonate type cationic synthesis enzyme. We’ll tell you more about this compound (cas:53636-17-2).
Novel optically active carbonate-type cationics were designed and synthesized via a green method. A series of n-alkyl N,N-dimethylaminoalkyl carbonates was prepared via a two-step successive carbonate exchange reaction of di-Ph carbonate with 1-alkanol followed by the reaction of the optically active or racemic amino alc. in the presence of triethylamine. The quaternarization of the N,N-dimethylamino group was carried out using Me iodide. Furthermore, optically active cationics were prepared by the lipase-catalyzed enantioselective hydrolysis of the racemic cationics. Carbonate-type cationics having an isopropylene linkage showed high hydrolytic stability. They exhibited surfactant properties similar to those of the corresponding racemic cationics. Although no significant differences in the antimicrobial activities were observed owing to the stereochem. of the cationics, the biodegradability was strongly influenced by the stereochem. Some optically active cationics were rapidly biodegraded by activated sludge.
From this literature《Chemo-enzymatic synthesis and properties of novel optically active cationics containing carbonate linkages》,we know some information about this compound(53636-17-2)Safety of (S)-1-(Dimethylamino)propan-2-ol, but this is not all information, there are many literatures related to this compound(53636-17-2).
