Isatin derivatives potentially act on various biological targets. In this article, a series of novel
isatin-hydrazones were synthesized in excellent yields. Their cytotoxicity was tested against …

Organic compounds containing azines, di-imines, or bis-Schiff-bases have two azomethine (-
CH= N-) functional groups associated with a bridging component. These constituents have …

The reaction of isatin 1 with benzaldehyde and a sec‐amine or the appropriate aldimine
afforded the N‐Mannich bases 2–3 and the bis‐base 4. Treatment of 1 with glutaric …

Abstract A series of 6-acetyl-2, 4-diaryl-2, 3, 4, 5-tetrahydro-1, 2, 4-triazines (2a–2f) was
synthesized by double Mannich reaction of the hydrazone 1a or 1b with formaldehyde and …

An efficient and easy procedure is developed for the synthesis of isatin aldazines or bis-
Schiff bases of isatin, catalyzed by a proton exchanged Algerian montmorillonite clay (MMT …

The hydrazide-hydrazones 6a–d and 7a, b were obtained by treating isatin (1) or its
Mannich base 2 with hydrazides incorporating piperidine, morpholine, and piperazine units …

Abstract New series of 2‐(benzylthio)‐6‐phenyl‐4 H‐imidazo [1, 2‐b][1, 2, 4]‐Triazoles and
benzylthio‐4 H‐1, 2, 4‐Triazolo iminoimdoline‐2‐ones have been synthesized via a one …

The crystal structures of four azines, namely 1-3-bis (4-methoxyphenyl)-2, 3-diaza-1, 4-
butadiene, 1, 1, 3-bis (2, 3-dimethoxyphenyl)-2, 3-diaza-1, 4-butadiene, 2, 1, 3-bis (2 …

A series of tetrahydropyrimidines and bis‐(tetrahydropyrimidines) was synthesized by
Mannich reaction of sec‐emaminones with formaldehyde and the appropriate amine or …
