TL;DR: Amberlyst-15 has been found to be an efficient catalyst for the synthesis of 1,8-dioxo-decahydroacridines in excellent yields as mentioned in this paper.

TL;DR: Two new flavanoids, 5,7-dimethoxy-3',4'-methylenedioxyflavanone and isobonducellin along with 2'-hydroxy-2,3,4',6'-tetramethoxychalcone and bondu cellin were isolated from the aerial parts of Caesalpinia pulcherrima and were settled mainly by interpretation of their 1D and 2D NMR spectra.

TL;DR: In this paper, α-bromination of carbonyl compounds (cyclic and acyclic ketones, amides and β-ketoesters) has been achieved efficiently by treatment with N -bromosuccinimide (NBS) and catalyzed by silica-supported sodium hydrogen sulfate (NaHSO 4 ·SiO 2 ).

TL;DR: In this article, cross-Aldol condensation of aromatic aldehydes with cyclic ketones in the presence of catalytic amount of iodine at room temperature afforded α,α′-bis(substituted-benzylidene) cycloalkanones in high yields.

TL;DR: Chemical investigation on Caesalpinia crista afforded two new diterpenoids, 6beta-cinnamoyloxy-7 beta-acetoxyvouacapen-5alpha-ol and 6beta,7beta-dibenzoyl Oxyvouacs-5 alpha-ol along with several known constituents and the cytotoxicity of these compounds was measured on two different cancer cell lines.
