Visibility and impact of the Indian Journal of Chemistry, Section B during 2005-2009 using scientometric techniques

 

This is the first scientometric assessment of the visibility and impact of the Indian Journal of Chemistry, Section B for serving the needs of researchers, mainly from India, in the area of organic and medicinal chemistry. All papers published in this journal during 2005 to 2009 have been studied using various scientometric criteria like geographical distribution, citations received each year and authorship patterns.

Synthesis of some new 3,4-disubstituted pyrroles and pyrazoles from E-1-(arylsulfonylethyl­sulfo­nyl)-2-arylethene

 

The sulfonyl activated olefin, E-1-(arylsulfonyl­ethyl­sulfonyl)-2-arylethene 7 has been used as a synthon to develop a new class of pyrrole and pyrazole derivatives by 1,3-dipolar cycloaddition of TosMIC and diazo­methane.

Microwave assisted synthesis and antibacterial properties of some new 2-alkyl/aryl-(6-substi­tuted­coumarin-3-yl)imidazo[2,1-b][1,3,4]thia­dia­zoles

 

A series of 2-alkyl/aryl-(6-substitutedcoumarin-3-yl)imidazo[2,1-b][1,3,4] thiadiazoles 3a-o have been synthe­sized by reacting 3-(2-bromoacetyl)-6-substituted­coumarins 1 with various 5-alkyl/aryl-2-amino-1,3,4-thiadiazoles 2 under normal thermal condition as well as microwave irradiation. All the newly synthesized compounds have been tested for their antibacterial properties.

AM1 study of the electronic structure of 7-aminodeacetoxycephalosporanic acid (7-ADCA)

 

The geometry and electronic structure of 7-amino­deacetoxycephalosporanic acid (7-ADCA) have been fully optimized and calculated by semi-empirical molecular orbital AM1 method. The conformational analyses of mono- and di-protonated species have also been performed.

Molecular iodine mediated one step synthesis and antibacterial properties of some 3-aryl-6-(6-substituted-4-methylcinnolin-3-yl)-7H-1,2,4-tria­zolo[3,4-b][1,3,4]thiadiazines

 

3-Aryl-6-(6-substituted-4-methylcinnolin-3-yl)-7H-1,2,4-triazolo[3,4-b][1,3,4]thiadiazines 3a-l have been synthesized directly in one step by iodine mediated condensation of 3-acetyl-6-substituted-4-methylcinnoline 1 with 3-aryl-4-amino-5-mercapto-1,2,4-triazoles 2.

Rational design, synthesis, SAR study of N-napthalen-1-yl-2-[4-(substituted phenyl)-pipera­zin-1-yl]-acetamides as atypical antipsychotic agents

 

Various N-napthalen-1-yl-2-[4-(substituted phenyl)-pipera­zin-1-yl]-acetamides were designed and synthe­sized on the basis of three-dimensional structural information provided by homology modeling studies of dopamine D2 and serotonin (5-HT) receptors and screened for antagonist activity at the target receptors and atypical antipsychotic profile.

Mild, efficient and economical oxidative deprotection of allyl aryl ethers

 

An efficient, economical procedure for the cleavage of allyl aryl ethers using a catalytic amount of iodine in dimethyl sulphoxide is described. Allyl ether of phenols is selectively deprotected in preference to alcohols. The reaction is highly regioselective and chemoselective.
