Synthesis of the anti-virus compound shuangkangsu's analogs.

Di-Zao Li et al.

Journal of Asian natural products research, 11(7), 613-620 (2010-02-26)

Four novel cyclic peroxide glucosides 15a, 15b, 16a, and 16b, optically pure analogs of shuangkangsu (1), which is an anti-virus natural product with an unusual skeleton isolated from the buds of Lonicera japonica Thunb, were first synthesized totally in six

3,4,5-Trisubstituted Furan-2(5H)-one Derivatives: Efficient one-pot Synthesis and Evaluation of Cytotoxic Activity.

W M Basyouni et al.

Drug research, 65(9), 473-478 (2014-09-11)

A series of 3,4,5-trisubstituted 2(5H)-furanone derivatives was synthesized through one-pot reaction of amines, aldehydes and diethyl acetylenedicarboxylate. Silica sulfuric acid efficiently catalyzes the 3-component reaction to afford the corresponding 2(5H)-furanones in high yields. The synthesized compounds were tested against HEPG2

Synthesis of pyrrolidinone derivatives from aniline, an aldehyde and diethyl acetylenedicarboxylate in an ethanolic citric acid solution under ultrasound irradiation

Hamideh A et al.

Green Chemistry, 18, 3582-3593 (2016)

Synthesis of novel highly functionalized 4-thiazolidinone derivatives from 4-phenyl-3-thiosemicarbazones.

Abdelmadjid Benmohammed et al.

Molecules (Basel, Switzerland), 19(3), 3068-3083 (2014-03-13)

We present herein the synthesis in good yields of two series of highly functionalized thiazolidinone derivatives from the reactions of various 4-phenyl-3-thio-semicarbazones with ethyl 2-bromoacetate and diethyl acetylenedicarboxylate, respectively.

Microwave Induced Stereoselective Synthesis of O--Vinyl Oximes using Acetylenic Esters as Efficient Michael Acceptors

Ankush M et al.

ChemistrySelect, 3, 9464-9468 (2018)

Diels-Alder reactivity of polycyclic aromatic hydrocarbon bay regions: implications for metal-free growth of single-chirality carbon nanotubes.

Eric H Fort et al.

Journal of the American Chemical Society, 131(44), 16006-16007 (2009-10-17)

A soluble bisanthene derivative, 4,11-dimesitylbisanthene, has been synthesized in three steps from bianthrone. In hot toluene, this bisanthene undergoes a clean Diels-Alder reaction with diethyl acetylenedicarboxylate to give a rearomatized 1:1 cycloadduct and, more slowly, a rearomatized 2:1 cycloadduct. In

Synthesis and Characterization of Novel Thiazolo[3,2-a]pyrimidine Derivatives and Evaluation of Antioxidant and Cytotoxic Activities.

Asieh Khalilpour et al.

Chemistry & biodiversity, 16(5), e1800563-e1800563 (2019-02-12)

A series of novel thiazolo[3,2-a]pyrimidines were synthesized and characterized by FT-IR, 1 H, 13 C-NMR and mass techniques. Their antioxidant activities were investigated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and the results showed that all the synthesized compounds exhibit good

Alkyne activation and polyhedral reorganization in benzothiazolate-capped osmium clusters on reaction with diethyl acetylenedicarboxylate (DEAD) and ethyl propiolate.

Kh Mahid Uddin et al.

Dalton transactions (Cambridge, England : 2003), 46(39), 13597-13609 (2017-09-28)

The reactivity of the face-capped benzothiazolate clusters HOs

Enhanced toxicity of the protein cross-linkers divinyl sulfone and diethyl acetylenedicarboxylate in comparison to related monofunctional electrophiles.

James D West et al.

Chemical research in toxicology, 24(9), 1457-1459 (2011-08-05)

Previously, we determined that diethyl acetylenedicarboxylate (DAD), a protein cross-linker, was significantly more toxic than analogous monofunctional electrophiles. We hypothesized that other protein cross-linkers enhance toxicity similarly. In agreement with this hypothesis, the bifunctional electrophile divinyl sulfone (DVSF) was 6-fold
