Organic reactions in ionic liquids: Ionic liquid-accelerated cyclocondensation of α-tosyloxyketones with 2-aminopyridine
Xie, Yuan-Yuan,Chen, Zhen-Chu,Zheng, Qin-Guo
, p. 1505 - 1508 (2002)
The room temperature ionic liquid n-butylpyridinium tetrafluoroborate (BPyBF4) is used as a 'green' recyclable alternative to classical molecular solvents for the cyclocondensation of α-tosyloxyketones with 2-aminopyridine. Significant rate enh
Modified one-pot multicomponent diastereoselective synthesis of trans-2,3-Dihydrofuro[3,2-c]coumarins via in situ-generated α- tosyloxyketones

, p. 1802 - 1807 (2013)
A modified protocol for diastereoselective synthesis of differently substituted trans-2,3-dihydrofuro[3,2-c]coumarins is developed via, a one-pot multicomoponent reaction starting from aromatic aldehydes, 4-hydroxycoumarin, and α-tosyloxyacetophenones wit
Diastereoselective Alkene Hydroesterification Enabling the Synthesis of Chiral Fused Bicyclic Lactones
Shi, Zhanglin,Shen, Chaoren,Dong, Kaiwu
supporting information, p. 18039 - 18042 (2021/11/16)
Palladium-catalysed diastereoselective hydroesterification of alkenes assisted by the coordinative hydroxyl group in the substrate afforded a variety of chiral γ-butyrolactones bearing two stereocenters. Employing the carbonylation-lactonization products as the key intermediates, the route from the alkenes with single chiral center to chiral THF-fused bicyclic γ-lactones containing three stereocenters was developed.
A convenient [hydroxy(tosyloxy)iodo]benzene-mediated one-pot synthesis of 2-arylimidazo[2,1-b[benzothiazoles
Sumran, Garima,Aggarwal, Ranjana
, p. 170 - 177 (2015/10/20)
Several 2-arylimidazo[2,1-b]benzothiazoles (4) have been conveniently synthesized in one-pot reactions via α-tosyloxylation of enolizable ketones (1) using [hydroxy(tosyloxy)iodo]benzene 2 in acetonitrile, followed by treatment with 2-amino-6-(substituted
