, p. 39 - 49 (2018/10/26)
Bis(6-amino-1,2-dihydropyridine-3,5-dicarbonitriles) containing thioether linkages are prepared via the condensation of bis(cyanoacetamides) with α-substituted cinnamonitriles in the presence of piperidine. The target compounds can also be obtained via a three-component reaction of bis(cyanoacetamides) with two equivalents of both aldehydes and malononitrile in ethanol containing piperidine as a base.
Zinc oxide catalyzed solvent-free mechanochemical route for C-S bond construction: A sustainable process
Md. Khaja Mohinuddin,Gangi Reddy
, p. 1207 - 1214 (2017/12/07)
A zinc oxide catalyzed solvent-free mechanochemical process has been developed for the rapid construction of C-S bonds by using a nucleophilic substitution reaction (SN2 mechanism) that involves a variety of thiols and phenacyl/ benzyl/alkyl bromides. Notable advantages of this method in-clude its broad substrate scope, clean reaction profile, safety, scalability, high product yields at ambient conditions, and the recyclability of the catalyst. Furthermore, the prepared compounds are valuable building blocks for the synthesis of various biologically active molecules.
Synthesis and evaluation of bifunctional chelating agents derived from bis(2-aminophenylthio)alkane for radioimaging with 99mTc
Chhikara, Bhupender S.,Kumar, Nitin,Tandon, Vibha,Mishra, Anil K.
, p. 4713 - 4720 (2007/10/03)
Novel bifunctional chelating agents bearing an aromatic rigid backbone have been synthesized and characterized on the basis of spectroscopic techniques. These macrocyclic multidentate chelating agents were conjugated with monoclonal antibody which forms stable complexes with 99mTc with high radiochemical purity.
KF-alumina immobilized in ionic liquids: A novel heterogeneous base for heterocyclization of alkylsulfanylphenylamines into 1,4-benzothiazine
Chhikara, Bhupender S.,Mishra, Anil K.,Tandon, Vibha
, p. 1057 - 1065 (2007/10/03)
A rapid and convenient synthetic methodology for the cyclocondensative transformation of various alkylsulfanylphenylamines with bromoacetyl bromide by supporting on KF-alumina in ionic liquids [bmim] [Br] and [bmim][BF 4] has been developed to obtain 3-oxo-1,4-benzothiazine in good yields. The product is easily obtained by extraction with ethyl acetate and concentrating under vacuum. Easy recovery of ionic liquid and use in consecutive reactions is also reported.
