The title compound, C(13)H(11)FO(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 2-fluoro-benzaldehyde in ethanol. In the crystal structure, mol-ecules are linked into chains by weak inter-molecular C-H⋯O hydrogen bonds.

1. Methanobacterium omelianskii was grown on (14)CO(2) and unlabelled ethanol, or on [1-(14)C]- or [2-(14)C]-ethanol and unlabelled carbon dioxide. The cell protein was hydrolysed and certain of the amino acids were isolated and degraded. 2. Carbon from both carbon dioxide and ethanol is used for biosynthesis of amino acids, and in most cases ethanol is incorporated as a C(2) unit. Ethanol carb...

The title compound, C(13)H(12)O(5), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 4-hy-droxy-benz-alde-hyde in ethanol. The 1,3-dioxane ring is in a distorted boat conformation. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(20) rings.

The title compound, C(13)H(11)FO(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 4-fluoro-benz-alde-hyde in ethanol. The 1,3-dioxane ring adopts an envelope conformation. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

The title compound, C(19)H(18)Cl(2)O(8), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 2,4-dichloro-benzaldehyde in ethanol. The two 1,3-dioxane rings exhibit boat conformations. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds, forming chains parallel to the a axis.

Synthesized of novel metal (II)- tetra-4-(N,N-dimethyl phenyl) methan-imine phthalocyanines (MTDMPhImPc) [ M = Co, Ni, Cu, Zn] by an effective and suitable method. The tetra-nitrophthalocyanines converted into aminophthalocyanines reduction. Than amino derivatives bearing to form tetra substituted 4-(N,N-dimethyl methane-imine complexes. These compounds were characterized FTIR, elemental analys...

The effects of carcinogenic heterocyclic amines and beta-carbolines on 5-hydroxytryptamine-induced human platelet aggregation, on the uptake of 5-hydroxytryptamine by platelets, and on human monoamine oxidase activity were investigated. Of the dietary carcinogens and beta-carbolines studied, carcinogenic tryptophan pyrolysis products had greater pharmacological activities than other heterocycli...

In this study, we investigated carbon feedstock decomposition conditions on the synthesis of single-walled carbon nanotubes (SWNTs) by chemical vapour deposition. We simulated gas-phase thermal decomposition of ethanol and dimethyl ether (DME) at typical SWNT growth conditions using the chemical kinetic model, and confirmed the reaction trends and primary products using Fourier transform infrar...

We discovered structurally novel human calcium-sensing receptor (CaSR) allosteric agonists and compared their pharmacology to phenylalkylamine calcimimetics. 1-Benzothiazol-2-yl-1-(2,4-dimethyl-phenyl)-ethanol (AC-265347) activated CaSR signaling in cellular proliferation and phosphatidylinositol (PI) hydrolysis assays with potencies of 30 and 10 nM, respectively. (S)-1-Benzothiazol-2-yl-1-(2,4...

The development of contact hypersensitivity (CHS) greatly depends on the allergenicity of the inducing agent. However, various cofactors are known to influence the outcome of the response as well. From this perspective, we have compared the effects of five different vehicles: acetone, ethanol, dimethyl formamide (DMF), dimethyl sulfoxide (DMSO), and a 4 to 1 mixture of acetone and olive oil (AO...
