Synthesis of Unnatural Diethyl 2-Hydroxysuccinate From 2,3-Dihydroxysuccinic Acid As a Starting Material for Annonine Building Blocks

Autor: Jewad K. Shneine

Publikováno v: Al-Nahrain Journal of Science. 21:30-37

Since Annonin I is considered as a biological active natural product, this work concerns on the synthesis of the side chain of this biologically important molecule as a part of total synthesis of the whole molecule. As a result of our retrosynthetic

Evaluation the Corrosion of Mild Steel Rings in Simulated Conditions of Natural Gas Transportation

Autor: Jewad K. Shneine

Publikováno v: Journal of Al-Nahrain University - Science. 20:42-48

Corrosion of steel rings (steel tubes) under natural gas production conditions has been studied in a 2 L glass autoclave. Steel tubes, axially constructed with cavities of aspect ratios 3×1 mm, were exposed to CO2 saturated chloride salt solutions i

SYNTHESIS AND CHARACTERIZATION OF NEW N-TERMINAL BCHAIN MODIFIED HUMAN INSULIN ANALOGUES

Autor: Jewad K. Shneine

Publikováno v: Journal of Al-Nahrain University Science. 13:23-30

New human insulin analogues were synthesized by fragment condensation reactions of N A1 , N B29 Msc protected native human insulin of different B-chain lengths with the dipeptide Boc-AsnThr-OH. Edman degradation was used to obtain shortened B-chain i

THEORETICAL STUDY OF CONCERTED DIELS-ALDER REACTIONS BETWEEN DIMETHYL 1,2,4,5-TETRAZINE-3,6-DICARBOXYLATE AND DIENOPHILES

Autor: Jewad K. Shneine, Mehdi Salih Shihab, Shaima Mohamad Ali Mahmood

Publikováno v: Journal of Al-Nahrain University Science. 12:14-23

Computational study at different levels of quantum calculations (AM1, PM3 and ab initio (HF/3-21G)) where preformed on the inverse-demand synchronous concerted Diels-Alder reactions between dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate as a diene and
