Palladium catalyzed transformation and antimicrobial screening of novel angular azaphenothiazines

Base mediated condensation reaction between 2-amino-5-bromopyrazine-3[4H]-thione and 7-chloro-5,8-quinolinequinone under anhydrous condition gave 9-bromo-1,8,11-triaza-5H-benzo[a]phenothiazin-5-one. Palladium catalyzed cross-coupling reaction between 9-bromo-1,8,11-triaza-5H-benzo[a]phenothiazin-5-one and four arylated halogeno compounds utilizing Heck-Mizoroki protocol furnished 6-substituted derivatives of the angular tetracyclic heterocycle. Structures were assigned based on spectroscopic and elemental analytical data. Antimicrobial screening of these compounds showed they were biologically active.

Crystallographic characterisation of Ti(iv) piperazine complexes and their exploitation for the ring opening polymerisation of rac-lactide

In this paper a series of eight Ti(iv) piperazine based complexes have been prepared and fully characterised in the solid-state by X-ray crystallography and in solution via NMR spectroscopy. In the solid-state either Ti 2(L)(OiPr)su

Simple synthesized Mannich bases as ligands in Cu-catalyzed N-arylation of imidazoles in water

1,4-Bis(2-hydroxy-5-methoxybenzyl)piperazine and its analogues were used as efficient ligands for CuI-catalyzed N-arylation of imidazoles with aryl halides in water under mild conditions (120 °C for 12 h) with 10 mol% of CuI, 20 mol% of the Mannich base, and two equivalents of KOH or K2CO 3 in the presence of 10 mol% phase transfer catalyst (n-Bu) 4NBr. A variety of products were synthesized in moderate to excellent yields using this inexpensive catalytic system. Springer-Verlag 2010.
