The linear polymerisation of B-dichloro-N-tri-(2,6-dimethylphenyl)borazole through the aromatic diamines, m- and p-phenylenediamine,p,p′-diaminodiphenylmethane, and benzidine, and the heterocyclic diamines, piperazine and ammeline, has been investigated and the range and degree of plasticity, stability in air, and hydrolytic and thermal stability of the linearpolyborazoles formed have been compared
3‐(Thiocarbazoyl‐thio)‐propionsäuren 1 wurden aus Hydrazinderivaten, Schwefelkohlenstoff und β‐Propiolactonen dargestellt und nach verschiedenen Methoden, überwiegend mittels Acetanhydrid unter saurer Katalyse, zu den neuartigen 3‐Amino‐2‐thioxo‐tetrahydro‐1,3‐thiazin‐4‐onen 2 cyclisiert.

We report on the design, synthesis, and in vitro evaluation of new quinoline-5,8-dione and hydroxynaphthoquinone derivatives. The synthesized compounds were evaluated for in vitro antimalarial activity against Plasmodium falciparum. Of the 15 compounds, 7a-c, 8a, 9b, 11, and 15 were effective in growth inhibition with IC50 values of below 5 mu M. (C) 2012 Elsevier Masson SAS. All rights reserved.
