Preparation of N-Substituted Hydroxylamines from Oxaziridines

Preparation of N-Substituted Hydroxylamines from Oxaziridines

Date: January 1968
Creator: Truitt, Sharon G.
Description: In many series of compounds, intensity of biological activity and chemical reactivity are proportional. Generally whenever a alkyl group replaces a reactive hydrogen atom, as would be the case for an N-substituted hydroxylamine as compared to hydroxylamine, the over-all biological activity of the resulting compound is lower than that of its nonalkylated analogue. Since toxicity and physiological activity are not proportional, this comparison can only suggest possible types of derivatives to prepare and test.

Synthesis of Selected 2-imidazolines

Date: June 1966
Creator: Maurer, Larry Eugene
Description: Since Djerassi and Scholz found that 2-(aryloxy-methyl)imidazolines and their hydrochloride salts exhibit vasoconstrictive properties, the 1,2-(I) 1,3-(II) and 1,4-bis-(2-imidazolinylmethoxy) benzene (III) analogs (Fig. 1, p.2) were chosen for synthesis in order to test them for their effective vasoconstrictive characteristics and for whatever other physiological properties they might exhibit.

The Synthesis of Benzo(d)pyrido(a)-benzimidazole-5,12-quinone

Date: May 1955
Creator: Cooper, James Erwin
Description: The present investigation yielded an orange product upon refluxing 2-butyramido-3-chloro-1,4-naphthoquinone and 2-aminopyridine in ethanol. When this material was purified, by recrystallization from glacial acetic acid, the melting point was 306 [degrees]. This compound has been shown to be benzo(d)pyrido(a)-benzimidazole-5,12-quinone by the present investigation.

Conformational Analogs of Some Phytoactive Compounds

Conformational Analogs of Some Phytoactive Compounds

Date: August 1973
Creator: Skelton, Wm. Paul
Description: In an effort to determine if there is a specific conformational structure which is most effective at the appropriate active physiological site, the synthesis of a group of sterically restricted analogs was undertaken. A portion of the polymethylene carbon skeleton of glutaric acid was replaced by selected aromatic carbons in benzenedicarboxylic acids to produce a series of ridged conformers, and the relative plant growth regulating properties of these derivatives were determined.
