    The synthesis of ()-2,3,5-trihydroxyphenylpropene and its 4-chloro-(), 6-chloro-(), and 4,6-dichloro- derivatives is described. The routes involve the key intermediates, methyl 2,3,5-tribenzyloxybenzoate and methyl 2,3,5-tribenzyloxychlorobenzoate which were prepared from vanillin and 3,5-dimethox Jump to main content. Synthesis and Derivatives of cy, y-Diketooctanoic Acid Ethyl a!,r-Diketo-n-octanoate-As starting material for the Claisen con- densation, n-butyl methyl ketone was prepared via the acetoacetic ester synthesis (15); the ethyl oxalate was an Eastman product.

New procedures are described for the synthesis of α,β‐ethylenic and acetylenic aldehydes from 2‐butene‐ and 2‐butyne‐1,4‐diol, respectively (see Scheme 1).These are applied to the preparation of a particular δ‐acetylamino‐α,β‐ethylenic aldehyde ((E)‐5) as well as of its acetylenic analogue On heating in the presence of a silyl enol ether, the former undergoes a Cited by: Abstract 1,2-Dideoxyribose 5-O-succinate, a component of solid support employed in the synthesis of ribozymes, was synthesized from thymidine.

The key step was elimination of nucleobase from 2 to afford glycal 3. A number of catalysts for this reaction were tested, resulting in improved and scaleable synthesis. Hydrogenation of the resulting glycal afforded 1,2-dideoxyribose derivative 4 in a Cited by: 2.

In order to model and understand these biological properties and to develop new chemotherapeutic agents based upon the 1,4-DHP motif, considerable effort has been devoted to establish efficient and rapid methods for their synthesis. 1,4-DHPs are generally synthesized using the Hantzsch method, which involves cyclocondensation of an aldehyde, a.

A series of novel 4,6-di(substituted)amino-1,2-dihydro-1,3,5-triazine derivatives designed to have ClogP of − was synthesized and evaluated for their antiseptic properties by MIC and MBC tests against Gram-positive and Gram-negative bacteria, including MRSA, VRE, and P.

A novel series of 5-(5-substituted-1,3,4-oxadiazolyl)benzene-1,2,3-triols (3n-z) was designed, synthesized, and evaluated for its potential antioxidant activities.

Structural modifications at position 5 of the 1,3,4-oxadiazole scaffold (linked to a fixed antioxidant 3,4,5-trihydroxyphenyl moiety at position 2 of the ring) was expected to give new 1,3,4-oxadiazole derivatives with a wide.

Chloral cyanomethylhemiacetal is converted to 2-trichloromethylimino-1,3-dioxolane under the influence of hydrogen chloride or pyridine. Acetone cyanohydrin reacts with chloral to give 2-trichloromethylimino-5,5-dimethyl-1,3-dioxolane, the hydrochloride of which in water gives 2-trichloromethyloxo-5,5-dimethyl-1,3-dioxolane.

2-[(Dialkylcarbamoyl)methylene]-2,3-dihydrobenzo[1,4]dioxine and 3-[(dialkylcarbamoyl)methylene]-3,4-dihydro-2H-benzo[1,4]oxazine derivatives (3 and 5, respectively) were synthesized for the first time starting from readily available 2-propynyloxyphenols 1 and 2-propynyloxyanilines 4, respectively, through tandem oxidative aminocarbonylation of the triple.
