Synthesis of vicinal diamino-endo, cis-norbornene derivatives
Hossain, Delwar,Lavoie, Gino G.
experimental part, p. 1200 - 1210 (2012/04/10)
The synthesis of 2,3-disubstituted-endo,cis-norborn-5-ene derivatives is described. Cyclic ureas and cis vicinal diamines substituted with p-tolyl and perfluorophenyl rings were prepared. The use of potassium carbonate as an innocuous CO source for the formation of a cyclic urea was demonstrated. Copyright Taylor & Francis Group, LLC.

-
Page/Page column 25, (2008/12/07)
A method for repelling arthropods involving treating an object or area with an arthropod repelling effective amount of at least one compound having the formula wherein X is O, S, NH, N-NH2, N-CH3 or CH2, R' is H or alkyl, R" is alkyl, n is 0, 1, 2, 3 or 4, and mixtures thereof, optionally including a earner material or earner. The compound is preferably selected from homopiperazine, 1-methylhomopiperazine, 1-methylpyrrolidine, (R)- (-)-2-methylpiperazine, (S)-(+)-2-methylpiperazine, 2-methylpiperazine, 1 -methylpiperazine, pyrrolidine, 1-methylpiperidine, piperidine, 1-ethylpiperazine, 1-methylimidazolidine, 1- methylthiomorpholine, 1,4-dimethylpiperazine, homopiperidine, imidazolidine, 4- methylpiperidine, thiomoφholine, l-amino-4-methylpiperazine, 4-methylmoipholine, azocane, 2,6-dimethylpiperazine, 2,5-dimethylpiperazine, piperazine, 1-methylhomopiperidine, or mixtures thereof.

Lithiation studies with diacylimidazolidines, diacylhexahydropyrimidines, and triacylhexahydro-1,3,5-triazines indicate that no substantial increase in carbanion stability occurs as a result of the introduction of the second stabilizing group.Relative energies are calculated for three conformers of lithiated diformylimidazolidine, six conformers of lithiated diformylhexahydropyrimidine, and eight conformers of lithiated triformylhexahydro-sym-triazine.For the six-membered rings, conformers with equatorial lithium are always more stable those those with axial lithium.Although equatorial syn-syn conformers (with double O-Li co-ordination) are more stable than equatorial syn-anti, the difference is significantly less than that found between the corresponding syn-anti and (least stable) anti-anti conformers.
