Treatment of acetyl- 1,4-benzoquinone with isoprene gave the corresponding regioselective adduct (I). Rearrangement of the adduct (1) in pyridine and methanol gave 2-acetyl-5, 8-dihydro-6-methyl- 1,4-dihydroxynaphthalene (2). Silver oxide oxidation of the rearranged product (2) gave 2-acetyl-5,8-dihydro- 6-methyl- 1,4naphthalenedione (3). Regioselective addition of trans-piperylene to this...

Research was conducted to determine whether Leuconostoc mesenteroides starter cultures with and without malolactic activity (MDC and MDC, respectively) influenced sensory and chemical properties of sauerkraut. No sensory differences were found between MDC and MDC sauerkraut (P 0.05). In addition, sulfur compound profiles of the resulting sauerkraut were nearly identical. Brining at lower NaCl (...

In the title complex, [Mn(C(4)H(5)O(2))(C(27)H(27)N(7))(C(3)H(7)NO)]ClO(4)·C(3)H(7)NO, the Mn(II) ion is seven-coordinated in a distorted monocapped trigonal-prismatic geometry formed by a tetra-dentate tris-(1-methyl-1H-benzimidazol-2-ylmeth-yl)amine mol-ecule, a bidentate 2-methacrylate anion and a dimethyl-formamide mol-ecule. The methyl groups of the coordinated dimethyl-formamide mol-ecule...

The title compound, C(21)H(21)N(5)O(2), is a 1,4-dimethyl-1,2,3-triazole having dimethyl-benzodiazepindione and phenyl substituents on each methyl group; the substituents are positioned on opposite sides of the five-membered ring. The seven-membered fused-ring of the larger substituent adopts a boat-shaped conformation (with the methine C atom as the prow).

The synthesis and application of dimethyl carbonate (DMC) are achieving increasing importance due to its low toxicity and versatile reactivity. DMC can be used as environmentfriendly intermediate and starting material for organic synthesis via carbonylation and it can replace methylating agents such as dimethyl sulphate and methyl halides [1–3]. DMC is also being considered as a component for r...

The title compound, (C(2)H(8)N)(C(5)H(12)NO)[ZnCl(4)], was synthesized by hydro-thermal reaction of ZnCl(2) with 4-methyl-morpholine in a dimethyl-formamide solution. The asymmetric unit is composed of half a [ZnCl(4)](2-) anion, half a 4-methyl-morpholin-4-ium cation and half a dimethyl-ammonium cation, all located on mirror planes parallel to ac. All the amine H atoms are involved in inter-mo...
