AOT-based microemulsions accelerate the 1,3-cycloaddition of benzonitrile oxide to N-ethylmaleimide

, p. 6118 - 6123 (2006)
We studied the 1,3-dipolar cycloaddition of benzonitrile oxide to N-ethylmaleimide in AOT/isooctane/water microemulsions at 25.0 °C and found the reaction rate to be roughly 150 and 35 times greater than that in isooctane and pure water, respectively. The
Ionic liquids: Just molten salts after all?

While there has been much effort in recent years to characterise ionic liquids in terms of parameters that are well described for molecular solvents, using these to explain reaction outcomes remains problematic. Herein we propose that many reaction outcom

Synthesis was developed of 2-(10-undecenoyl)cyclohexane-1,3-diones containing in the side chain keto and hydroxy groups and a phenyl substituent. The synthesis is underlain by a nitrile oxide approach. The scheme included isoxazole synthesis for the prote

Abstract: Regioselective synthesis of some novel 7-bromo-2H-benzo[b][1,4]oxazin-3(4H)-one linked isoxazole hybrids via copper(I) catalyzed one-pot reaction of various aromatic aldehydes with 7-bromo-4-(prop-2-yn-1-yl)-2H-benzo[b][1,4]oxazin-3(4H)-one was developed. The structures of the compounds that are synthesized are confirmed by 1H NMR, 13C NMR, and mass spectra. All the hybrids have been tested for their in vitro anticancer activity against four human cancer cell lines, including HeLa, MCF-7, A549, and PC3. Three of the compounds exhibited remarkable anticancer activity compared to standard drug etoposide. Molecular docking studies with EGFR also strengthened the in vitro anticancer activity.
Reactions of 1,2,4-Oxadiazole[4,5-a]piridinium Salts with Alcohols: the Synthesis of Alkoxybutadienyl 1,2,4-Oxadiazoles

1,2,4-Oxadiazole[4,5-a]piridinium salts add alcohols and alkoxides to undergo electrocyclic ring opening affording alkoxybutadienyl 1,2,4-oxadiazole derivatives. The pyridinium salts represent a special class of Zincke salts that are prone to rearrange to give alkoxybutadienyl 1,2,4-oxadiazoles when treated with suitable nucleophiles or, alternatively, to give pyridones in the presence of bicarbonate. The pivotal tuning of the experimental conditions leads to a straightforward synthesis of valuable 1,2,4-oxadiazole derivatives. The mechanism is also discussed in the light of previous observations.
