Kamble, Atulkumar A.,Kamble, Ravindra R.,Kumbar, Mahadev N.,Tegginamath, Gireesh
, p. 1163 - 1174 (2016/07/06)
Quinoxaline derivatized with coumarin viz., 3a–f and with sydnones viz., 7a–0 were synthesized using pyridine as catalyst. Among the coumarin derivatives, 3a and 3b have been screened for anticancer activity against 60 human cancer cell lines at NIH (USA)
Bismuth triflate-catalyzed friedel-crafts acylations of sydnones
Mahoney, Jennifer,Turnbull, Kenneth,Cubberley, Mark
, p. 3220 - 3229 (2012/11/07)
Friedel-Crafts acylations of various 3-arylsydnones at the C4 position have been achieved in good yields using 4 equivalents of an alkyl anhydride and 25mol% each of bismuth triflate and lithium perchlorate in anhydrous acetonitrile at 95C. Acylations app
N-Bromosuccinimide (NBS) as Promoter for Acylation of Sydnones in the Presence of Acetic Anhydride under Neutral Conditions
Ghasemnejad-Bosra, Hassan,Haghdadi, Mina,Gholampour-Azizi, Issa
, p. 391 - 395 (2008/09/20)
Various 4 - acetyl sydnones (2) can be prepared by reaction of the corresponding 3-aryl sydnones (1) with acetic anhydride at ~110 °C promoted by N-Bromosuccinimide (NBS) as an effective reagent for acylation of sydnones under neutral conditions in satisf
1,3-Dibromo-5,5-dimethylhydantoin (DBH) as an efficient promoter for acetylation of 3-arylsydnones in the presence of acetic anhydride under neutral conditions
Azarifar, Davood,Bosra, Hassan Ghasemnejad,Tajbaksh, Mahmood
, p. 467 - 469 (2008/03/29)
(Chemical Equation Presented) 1,3-Dibromo-5,5-dimethylhydantoin (DBH) has been found to efficiently promote the conversion of various 3-arylsydnones to their 4-acetyl congeners in the presence of acetic anhydride under neutral conditions in satisfactory y
Acylation of sydnones with acetic anhydride in the presence of Montmorillonite K-10
Turnbull, Kenneth,George, Jones C.
, p. 2757 - 2764 (2007/10/03)
Various-4-acetyl sydnones 2 can be prepared in good yield by reaction of the corresponding 3-arylsydnones (cf. 1) with acetic anhydride at ~ 110°C catalyzed by Montmorillonite K-10. The reaction fails where an ortho-keto moiety is present; therein sydnone
