TL;DR: This article reviewed literature data on the title reactions and further examples given particularly with dialkylhydrazines and hydrazones, and new examples of dihydropyrazoloquinoline (27) and oxidopyrido[1,2-b]pyridazinium [(62)−(64)] ring systems are described.

TL;DR: In this article, single crystal X-ray studies of regioselectively synthesized fluoro-substituted dispiro-oxindole 9 revealed that the structure belongs to the monoclinic space group P21/n with four molecules in the unit cell.

TL;DR: NMR study is described to discriminate between structures of types 6 and 8 on the basis of (1)H-(13)C long-range correlation to give 1-functionalized cyclopent[b]indoles 15 and 16 with a high degree of stereoselectivity.

TL;DR: A data set of 181 diverse anionic surfactants has been investigated to relate the logarithm of critical micelle concentration to the molecular structure using Comprehensive Descriptors for Structural and Statistical Analysis (CODESSA Pro) software, and a fragment approach provided superior quantitative structure-property relationship (QSPR) models in terms of statistical characteristics and predictive ability.

TL;DR: Dihydropyrrolo[2′,1′:3,4]pyrazino[2,1-a]isoindolones as discussed by the authors were obtained in 76-81% yields by the reaction of 2-(1H-pyrrol-1-yl)ethylamine with 2-formylbenzoic acids.
