Studies of the reaction of the dione dimer of dimethylketene (1) with a series of o-aminophenols and with o-aminothiophenol have been carried out. These reactions give 2-[2-(2,4-dimethyl-3-oxopentyl)]benzoxazoles and -benzothiazole, respectively. Aliphatic 2- and 3-hydroxy- and 2- and 3-mercaptoamines yield 2-substituted 2-oxazolines, 5,6-dihydro-4H-1,3-oxazines, 2-thiazolines and 5,6-dihydro-4H-1
已经进行了二甲基乙烯酮(1)的二酮二聚体与一系列邻氨基苯酚和邻氨基硫基苯酚的反应的研究。这些反应分别得到2- [2-(2,4-二甲基-3-氧戊基)]苯并恶唑和-苯并噻唑。脂肪族的2-和3-羟基-和2-和3-巯基胺产生2-取代的2-恶唑啉,5,6-二氢-4 H -1,3-恶嗪,2-噻唑啉和5,6-二氢-4 H -1,3-噻嗪。
