Synthesis and biological activity of ferrocenyl furoyl derivatives
(Taylor & Francis Inc, 2017)
Due to the fact that ferrocene and furan derivatives have long been known to be one of the most biologically active compounds, preparation of their new derivatives might serve a very important purpose. Herein, five furoyl ...
Chiral phosphine oxide aziridinyl phosphonate as a Lewis base catalyst for enantioselective allylsilane addition to aldehydes
(Pergamon-Elsevier Science Ltd, 2015)
A series of chiral Lewis bases, phosphine oxide ferrocenyl aziridinyl methanol 1-4, phosphinyl aziridinyl phosphonates 5 and 6, and phosphine oxide aziridinyl phosphonates 7 and 8 were screened for allylsilane additions ...
Synthesis and biological evaluation of novel urea, thiourea and squaramide diastereomers possessing sugar backbone
(ELSEVIER SCI LTD, 2020)
A series of novel chiral 14 urea, thiourea and squaramide stereoisomers possessing carbohydrate backbones as well as amide functional groups was synthesized and characterized by their, H-1 NMR, C-13 NMR, FT-IR, HRMS, optical ...
Pyrolysis of Table Sugar
(Hindawi Publishing Corporation, 2013)
Table sugars were pyrolyzed at different temperatures (300, 400, and 500 degrees C) in a fixed-bed reactor. The effect of pyrolysis temperature on yields of liquid, solid, and gaseous products was investigated. As expected ...
Non-Acidic Mediated Friedel-Craft Reaction of Thiophene Using EtAlCl2
(Asian Journal Of Chemistry, 2013)
Since alkyl Lewis acids are Bronsted bases, they give a non-acidic reaction media. In this context, acylation of thiophene is investigated in the presence of EtAlCl2 and non-acidic media. Besides 8 examples of thiophene, ...
Copper-catalyzed asymmetric conjugate addition of diethylzinc to substituted chalcones using a chiral phosphine ligand
(Pergamon-Elsevier Science Ltd, 2011)
A series of chiral phosphine PFAM and phosphine oxide POFAM ligands were studied for the copper-catalyzed asymmetric diethylzinc addition to enones. One of these ligands, PFAM2, was an efficient catalyst with a variety of ...
1,4-diferrocenylbutane-1,4-dione
(Blackwell Publishing, 2008)
In the crystal structure of the title compound, [Fe-2(C5H5)(2)-(C14H12O2)], each carbonyl group is coplanar with the adjacent cyclopentadienyl ring, thus maximizing the pi-orbital overlap and electronic interactions between ...
