Liquid-phase parallel synthesis of 4-sulfanylbenzoic acid derivatives was written by Trifilenkov, A. S.;Il’in, A. P.;Kravchenko, D. V.;Dorogov, M. V.;Tkachenko, S. E.;Ivashchenko, A. V.. And the article was included in Izvestiya Vysshikh Uchebnykh Zavedenii, Khimiya i Khimicheskaya Tekhnologiya in 2005.Category: piperazines This article mentions the following:
Combinatorial libraries of substituted 4-sulfanylbenzamides and their derivatives were synthesized on the basis of 4-fluoro-3-nitrobenzoic acid. The procedure for nucleophilic substitution of fluorine by various thiols has been developed; the resulting 4-sulfenyl-3-nitrobenzoic acids were further converted into the corresponding esters and amides. Oxidation of the sulfide fragment with hydrogen peroxide afforded the corresponding sulfones. In the experiment, the researchers used many compounds, for example, 1-Propylpiperazine (cas: 21867-64-1Category: piperazines).
1-Propylpiperazine (cas: 21867-64-1) belongs to piperazine derivatives. Piperazine causes primary dermal irritation and skin burns at high concentrations. Piperazine also causes eye irritation in humans. Piperazine is an anthelminthic especially useful in the treatment of partial intestinal obstruction caused by Ascaris worms, which is a condition primarily seen in children. Piperazine hydrate and piperazine citrate are the main anthelminthic piperazines.Category: piperazines
