TL;DR: In this article, the use of β-cyclodextrin (β-CD) and (2-hydroxypropyl)-β-cyclodextrin (HPβ- CD) as mobile phase additives allowed to increase the proportion of water in the mobile phases without loss in the resolution or efficiency of the separations, leading initially to a considerable reduction of methanol and at later stage, to the development of a mobile phase containing only 30% of ethanol.

TL;DR: In this article, a one-pot, microwave-assisted protocol was developed for the synthesis of 5,6-dihydroquinazolinones that incorporate structural fragments from chalcones, acetylacetoacetate, ammonium formate and formamide.

TL;DR: This reaction constitutes the first example of an α,β-unsaturated N,N-dimethylhydrazone that behaves as a dienophile in a hetero Diels-Alder reaction.

TL;DR: In this paper, the reaction between 1,3-cyclohexanediones and chalcones (or their vinilogs) in the presence of 2.5-equiv of cerium(IV) ammonium nitrate afforded trans-2-aryl carbonyl-3-aryl (or styryl)-2,3,6,7-tetrahydrobenzofuran-4(5H)-ones in good to excellent yields and in high diastereoselectivities.

TL;DR: A small library of benzimidazole-fused pyrrolo[3,4-b]quinoline has been synthesized from readily available benzimids and various substituted arylamines in good to excellent yields utilizing an intramolecular Povarov reaction catalyzed by boron trifluoride diethyl etharate as the key final step.
