Zhao, Jie published the artcileSynthesis of stiripentol, Category: chlorides-buliding-blocks, the publication is Zhongguo Yiyao Gongye Zazhi (2013), 44(8), 747-748, database is CAplus.
Stiripentol, an anti-epileptic drug, was synthesized from piperonal and 3,3-dimethylbutan-2-one by Claisen-Schmidt reaction in the presence of phase transfer catalyst benzyltributylammonium chloride to give 4,4-dimethyl-1-[(3,4-methylenedioxy)phenyl]-1-pentene-3-one, which was subjected to reduction using NaBH4 with an overall yield of about 85%.
Zhongguo Yiyao Gongye Zazhi published new progress about 23616-79-7. 23616-79-7 belongs to chlorides-buliding-blocks, auxiliary class Phase Transfer Catalyst, name is N-Benzyl-N,N-dibutylbutan-1-aminium chloride, and the molecular formula is C22H18O2, Category: chlorides-buliding-blocks.
