Reactions of triterpenoid ketones with sulfur and morpholine under the conditions of Willgerodt-Kindler reaction

Abstract: 19/3,28-Epoxy-18ot-oleanan-3-one (I) when heated with sulfur in morpholine gives rise to 2-oxo derivative 1I, accompanied by a small amount of the starting ketone I. The reaction can be con­ trolled so that 2-oxo derivative 1I is formed almost exclusively. Derivatives lII- VII with a keto group and a further functional group in the position 2 and 3 also give 2-oxo derivative II. In the same manner 3-oxo-18ot-oleanan-28 -->-19/3-olide (XVIII) was converted to 2-oxo derivative XIX. \-oxo derivative VIII and A-nor-ketone IX do not react under these conditions. An addition of vicinal diamine into the reaction mixture leads to the formation of compounds XIII, XV-XVII, XX with a pyrazine cycle condensed with the ring A. The Willgerodt reaction is known as an advantageous method for the preparation ofthioamides of ro-arylalkanoic acids from aryl alkyl ketones; in the K.indler modifi­ cation of this method sulfur in boiling morpholine is used and in it aryl alkyl ketones afford thiomorpholides of acids l . The synthetic possibilities of this reaction in the chemistry of aromatic compounds are well investigated, but their application in the field of aliphatic and alicyclic ketones is much less known (see ref. l and the references therein). For example in the reaction of 3-alkanones with sulfur and morpholine the formation of a mixture of 2-alkanones and thiomorpholides of acids has been observed, i.e. a shift of the carbonyl group by one to two carbon atoms2 • Under similar conditions 4-heptanone and heptanal give a mixture of isomeric heptanones 3 • In the case of alicyclic ketones, when 4-methylcyclohexanone was reacted with sulfur in morpholine, the formation of a mixture of 2-, 3- and 4-methylcyclohexanone3 was observed. A similar shift of the keto group was also observed in camphor3 • In connection with our study of the reactivity of pentacyclic triterpenoids we ap­ plied the conditions of the Willgerodt-Kindler reaction to triterpenoid derivatives with a keto group in the ring A. As starting materials we used the following derivatives of I913,28-epoxy-18(X-oleanane and 18(X-oleanan-28~ 1913-olide: 3-oxo derivatives I and XVIlI, 2-oxo derivative II, I-oxo derivative VIII, A-nor-ketone IX and ketones with a double bond or a polar substituent in the ring A, III - VII.

This process is characterized in that a (meth)acrylic anhydride of formula: ##STR2## is reacted with a diamine of formula: ##STR3## in the presence of a polymerization inhibitor.

Anaerobic production and transformation of aromatic hydrocarbons and substituted phenols by ferulic acid-degrading BESA-inhibited methanogenic consortia

Abstract: Sewage sludge-derived methanogenic enrichments degrading ferulic acid as sole carbon and energy source were partially inhibited with 2-bromoethanesulfonic acid. The various intermediates and products formed under inhibition of methanogenesis were studied using gas chromatography/ mass spectrometry (GC/MS). In addition to aromatic, alicyclic, and aliphatic acids previously shown to be intermediates of ferulate degradation to CO2 and CH4, the following compounds were detected: toluene, ethylbenzene, phenol, p-cresol, 2-ethylphenol, catechol, and 3-hydroxy-4-ethylphenol. The character and the sequence of appearance of the compounds indicate that fermentative bacteria which initiate the anaerobic transformation of ferulic acid, in case of disruption of interspecies hydrogen transfer, dispose of electrons by converting part of the substrate to reduced derivatives. Aromatic hydrocarbons are further partially oxidized through hydroxylation of the ring (and, to a lesser extent, the side-chain), and partially reduced to saturated alicyclic rings. Some of these compounds seem to be gradually degraded to branched or straight- chain aliphatic acids. Some compounds, like catechol and ethylphenol, accumulate transiently or persistently in high concentrations (up to 16 mM carbon out of the initial concentration of 30 mM substrate carbon), indicating that hydroxylation of the aromatic ring might be an important metabolic reaction in these systems.

Optical recording medium

Abstract: PURPOSE:To obtain an optical recording medium which excels in heat resistance, hot deformation resistance, moisture proof and water proof and is also capable of control of the refractive index, by using the specific cast and hardened resin to a transparent substrate. CONSTITUTION:A transparent substrate is made of the cast and hardened epoxy resin containing epoxy resin, an organic polybasic acid anhydride, an hardening accelerator and a discoloring preventing agent. Both the refractive index and a glass shift point can be optionally controlled with simultaneous use of the aromatic epoxy resin and alicyclic epoxy resin. Thus a desired refractive index is obtained for the substrate. In particular, the refractive index of a hardened matter can be properly controlled by the miture rate with a mixture of the alicyclic epoxy resin and liquid bisphenol A type resin. A linear relation is secured between the mixture rate and the refractive index, and the ratio is preferably set within a range 9:1-1:9 between the aromatic resin and alicyclic resin for the substrate of an optical disk.

Synthesis of poly(benzothiazole)s by direct polycondensation of dicarboxylic acids with 2,5-diamino-1,4-benzenedithiol dihydrochloride using phosphorus pentoxide/methanesulfonic acid as condensing agent and solvent.

Abstract: A convenient method for the synthesis of poly(benzothiazole) of high molecular weights has been developed. These polymers were prepared readily by direct polycondensation of aliphatic, alicyclic, and aromatic dicarboxylic acids containing phenyl ether structures with 2,5-diamino-1,4-benzenedithiol dihydrochloride using phosphorus pentoxide/methanesulfonic acid (PPMA) as both a condensing agent and solvent. Polycondensations proceeded smoothly and were completed within several hours at 140°C to produce poly(benzothiazole)s with inherent viscosities up to 2.9 dl g−1. The thermogravimetry of the aromatic poly(benzothiazole)s showed 10% weight loss in air and nitrogen at 405—490°C and 450—595°C, respectively.

Abstract: 1. Radioactive 35S in 3′-phosphoadenosine 5′-phosphosulphate was incorporated into alicyclic, alkyl- and aryl-amines in the presence of hepatic 105 000g supernatants of female rats. 4-Phenylpiperazine, 4-pheny1-1,2,3,6-tetrahydropyridine (PTHP), 1,2,3,4-tetrahydroisoqumoline, N-methylbenzylamine, desmethylzotepine and desmethylzimeldine showed the highest conjugation with 35SO3 among the amines tested.2. Incorporation of 35SO3 into alicyclic and alkyl-amines was higher at pH 10.0 than at pH 7.4 but the incorporation into arylamines was the opposite. A greater amount of 35SO3 was incorporated into the secondary alkylamines than the corresponding primary amines.3. Radioactive reaction products were identified as N-sulphoconjugates of amines by comparison on t.l.e. with synthetic authentic compounds. Reaction products of desmethylimipramine (DMI) and PTHP in vitro were isolated as their sulphoconjugates, identified by comparison of field desorption mass spectra, u.v. spectra, retention time on h.p.l.c. and R...
