2. A Novel protocol for synthesis of Hantzsch 1, 4- dihydropyridines using PEG-400 as a reaction medium and under catalyst-free condition

Ali Ezabadi; Fatemeh Tosan

Volume 1, Issue 1 , Spring 2011, Pages 9-15

Abstract
  An efficient and expeditious catalyst-free procedure was developed for the one- pot synthesis of 1, 4-dihydropyridine derivatives via the three-component reaction of various aldehydes, ethyl acetoacetate, and ammonium acetate in PEG-400. The reaction was carried out at 110°С and the products were ...  Read More

4. Discussion on the regioselectivity of aminolysis of 5-bromo-2,4- dichloro-6-methylpyrimidine in ethanole

Abdolhassan Doulah; Hossein Eshtiagh-Hosseini; Masoud Mirzaei; Ali Fazlara

Volume 1, Issue 1 , Spring 2011, Pages 21-26

Abstract
  Crystallographic data analyses indicate that  three types of prolinium cations, along with two types of hydrogen  bonding,  produce and stabilize the helical structure of  triprolinium 12-phosphomolybdate. There are similarities between this organic-inorganic compound and peptides/proteins. ...  Read More

7. Reaction between 3-hydroxy pyridine alkyl isocyanides and dialkyl acetylenedicarboxylate: synthesis of 4H-chromenes

Mahsa Mahpeyma; Bita Mohtat

Volume 1, Issue 1 , Spring 2011, Pages 47-50

Abstract
  The reactive intermediate generated by the addition of tert-butyl and 1,1,3,3-tetramethyl butyl isocyanide and cyclohexyl isocyanide to dialkyl acetylenedicarboxylate was trapped by 3-hydroxy pyridine to produce highly functionalized 4H-chromenes in fairly good  yields.  Read More

8. An efficient synthesis of arylaminotetrazoles as via [2+3] cycloaddition of nitriles and sodium azide via solid acid catalysis

Abbas Teimouri; Alireza Najafi Chermahini

Volume 1, Issue 1 , Spring 2011, Pages 51-55

Abstract
  The [3+2] cycloaddition between various nitriles and sodium azide proceeds smoothly in the presence of zeolite and sulfated Zircona as effective catalyst and in the water and DMF/MeOH, to give the corresponding arylaminotetrazoles in good to high yields. The reaction most probably precedes through the ...  Read More
