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)

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 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

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

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

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.
