Microwave-assisted synthesis of azoniaspiro compounds using a novel catalyst, 1-aza-phenothiazine was written by Gupta, Archana;Sakhuja, Rajeev;Kushwaha, Khushbu;Jain, Subhash C.. And the article was included in Synthetic Communications in 2011.Computed Properties of C13H14BrNO2 This article mentions the following:
1-Aza-phenothiazine catalyzed the intramol. cyclization of N-(bromoalkyl)phthalimides in the presence of anhydrous K2CO3 to form spiro cyclic quaternary ammonium salts, namely azoniaspiro compounds, under microwave irradiation A novel and eco-friendly method was developed for the synthesis of azoniaspiro compounds, and the role of aza-phenothiazine as a catalyst in such reactions was established for the first time. In the future, this protocol can be extended to the synthesis of various substituted N-heterocycles by hydrolyzing the resulting azoniaspiro compounds In the experiment, the researchers used many compounds, for example, N-(5-Bromopentyl)phthalimide (cas: 954-81-4Computed Properties of C13H14BrNO2).
N-(5-Bromopentyl)phthalimide (cas: 954-81-4) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
