ジャーナル フリーDerivatives of N, N-dialkyl-N', N'-bis (2-chloroethyl) polymethylenediamine and some of their N, N'-dioxides were synthesized. These compounds are supposed to remain as cations even in physiological liquids contrary to N-methyl-bis (2-chloroethyl) amine, because the dialkylamino group in these molecules is far more strongly basic than bis (2-chloroethyl)-amino group. Relationship between anti-tumor activity and chemical and physical characteristics of these compounds are also discussed.抄録全体を表示PDF形式でダウンロード (936K) -

ジャーナル フリーThe structure of a photo-reaction product of luteoskyrin, designated lumiluteoskyrin, has been discussed. Lumiluteoskyrin, C30H20O12, dark purple crystals, m. p. above 360°, yielded a diacetate, C30H18O10 (OCOCH3)2, a tetraacetate, C30H16O6 (OCOCH3)4, and a hexa acetate, C30H14O6 (OCOCH3)6. On thermal degradation, lumiluteoskyrin gave islandicin and catenarin. On reduction with alkaline sodium dithionite, lumiluteoskyrin was not cleaved, while by the action of hydrochloric acid and zinc, it yielded islandicin. The positive magnesium acetate reaction and the ultraviolet and visible light absorption spectra showed that lumiluteoskyrin is a true quinone compound possessing a naphthazarin system in its molecule. On the basis of the chemical and spectral evidences, a structural formula (III) was proposed for lumiluteoskyrin and the photo-reaction mechanism was discussed.抄録全体を表示PDF形式でダウンロード (720K) -

ジャーナル フリーFormula (II) for the structure of kayaflavone was confirmed through the degradation of its triethyl ether with barium hydroxide, which afforded 2-hydroxy-4, 6-diethoxyaceto-phenone, a phenolic acid (IV) of m. p. 287∼288°, and anisic acid.抄録全体を表示PDF形式でダウンロード (347K) -

ジャーナル フリーHydrobenzoin cyclic phosphorochloridate was synthesized and isolated in a pure state. This compound was reacted with 2-(benzyloxycarbonylamino) ethanol, 1, 2, 3, 4-tetra-O-acetyl-β-D-glucose, and 2', 3'-O-isopropylideneadenosine, and the reaction products were submitted to hydrogenolysis to obtain the respective O-phosphate of the above three alcoholic compounds. Removal of the protective group from the phosphates thus obtained gave phosphorylethanolamine, D-glucose 6-phosphate, and adenosine 5'-phosphate, respectively.抄録全体を表示PDF形式でダウンロード (787K) -

ジャーナル フリー2-(Benzyloxycarbonylamino) ethyl hydrobenzoin cyclic phosphate (I), 2-(benzyloxycar-bonylamino) ethyl hydrobenzoin phosphate (II), and hydrobenzoin cyclic phosphate (III) were reacted with various concentrations of aqueous alkali and concentrated ammonia, and the hydrolysis products of these compounds were examined at intervals. From the results obtained by this kinetic study, it was concluded that the triester (I) does not take part as an intermediate in the alkaline hydrolysis of (II) to the final product of hydrobenzoin phosphate (IV).抄録全体を表示PDF形式でダウンロード (693K) -

ジャーナル フリーThe structure of substance A-VI, isolated by the writers and described in Part X, 1) was examined. This substance did not crystallize, but its acetate was obtained as needles, m. p. 237∼239°. By acid hydrolysis, it afforded dianhydrogitoxigenin, digitalose, and glucose. Its treatment with activated alumina and deacetylation with potassium hydrogencarbonate changed its acetate into 16-anhydro-digitalinum verum monoacetate. There-fore substance A-VI is formulated as 16ξ, 17α-gitoxigenin glucosidodigitaloside and it was named allo-digitalinum verum.抄録全体を表示PDF形式でダウンロード (543K) -

ジャーナル フリーHydrogenation of coriamyrtin with palladium catalysts resulted in formation of impure products which gave two new isomers of bromocoriamyrtin, β-bromocoriamyrtin, m. p. 248°(decomp.), and γ-bromocoriamyrtin, m. p. 203°, depending on the condition of the hydrogenation. Bromocoriamyrtin formerly obtained is now called α-bromocoriamyrtin. On hydrolysis with dilute sulfuric acid, the crude products from both hydrogenation gave the same dinitrophenylhydrazone which is an isomer of the dinitrophenylhydrazone of isocoriamyrtin. Hydrogenation with palladium catalyst under a stronger condition resulted in formation of an isomer of dihydrocoriamyrtin, m. p. 172°. From these results, formation of an isomer, which will be called neocoriamyrtin, by the hydrogenation of coriamyrtin with palladium catalyst was presumed. Neocoriamyrtin is considered to possess an isopropylidene group formed by transformation of the isopropenyl group in coriamyrtin. Unlike neopicrotoxinin, which gives aromatic picrotonol when heated in dilute mineral acid under mild conditions, the crude product which is presumed to contain neocoriamyrtin gave no aromatic derivative when heated in dilute mineral acid under various conditions. It was confirmed by chromatography and ultraviolet spectra that direct action of dilute mineral acid on coriamyrtin also gave no aromatic derivative.抄録全体を表示PDF形式でダウンロード (696K) -

ジャーナル フリー1) Although 3-ethynylmenthol and 2-ethynylcarbomenthol, among monocyclic compounds of camphor system, have been reported as undergoing Meyer-Schuster rearrangement in the main, the present series of experiments have clarified that the Rupe reaction also progresses in these compounds, same as in 1-ethynylcyclohexanol. 2) 2-Ethynyl-1, 3, 3-trimethyl-2-norborneol undergoes Meyer-Schuster rearrangement by treatment with hydrochloric acid and formic acid, but only the Rupe reaction takes place, accompanied by the Wagner rearrangement, by treatment with sulfuric acid. 3) 1-Methyl-2-ethynylnorborneol undergoes both Meyer-Schuster rearrangement and Rupe reaction, irrespective of the catalyst used. This compound is similar to monocyclic compounds in that it undergoes endocyclic dehydration during the Rupe reaction. 4) 2-Ethynylnorborneol dose not undergo the Meyer-Schuster rearrangement and only the Rupe reaction takes place, similar to monocyclic compounds in general.抄録全体を表示PDF形式でダウンロード (1229K) -
