N-(2-(2-(2-aminoethoxy)ethoxy)ethyl)−6-bromoquinazolin-4-amine (amine 3) The carbamate above (3.60 g, 7.91 mmol) was treated with HCl in 1,4-dioxane (40 mL, 160 mmol) at 25 °C under N2 and stirred at 25 °C for 2 h. The mixture was evaporated to dryn...
Dioxaneferrocenylimine Cyclometalated Compounds as Precursors to Novel Functionalized Di- and Tetranuclear Metallacycles Leading to 1,3-Double Palladation ... Reaction of the Schiff base ligands CpFe[η5-C5H2{C(H)O(CH2)3O}C(H)═NR] (R = 2,4,6-Me3C6H2, a; R = Cy, b) derived fro...
The material was then dissolved in a mixture of 1,4-dioxane (5 mL) and 4M HCl in 1,4-dioxane (5 mL). The mixture was stirred at room temperature for 3 h. The reaction mixture was concentrated. The desired product was purified by reverse phase HPLC to give (±)-N-(2-(3,3-di...
4 and Supplementary Fig. S12). Overall, these observations demonstrate that both potency and efficacy of the PQ compounds are differentially determined in part by the amino acid in position 41 of the minus side segment G in α1β1 and α1β3 receptors and thus strongly support the notion ...

This investigation centers on the preparation of new binary carbon sulfides based on the 1,2-dithiole-3-thione subunit as found in the precursor dithiolate C[sub 3]S[sub 5][sup 2[minus]]. Tricyclic S[sub 6]S[sub 8], 1, was obtained in high yield by thermal elimination of H[sub 2...
(the+/+minus the−/−profile) of the unusual VLC-PUFAs reveals photoreceptor-specific (positive-going) and retina-specific (negative-going) PC species. Red bars indicate molecules that are diagrammed inFig. 5, Blue bars indicate molecules that are diagrammed inSupplementary Fig. 3. In ...
The 100 percent effect of PCP is accordingly calculated to be total motility counts minus baseline. The response in groups receiving test compound is thus determined by the total motility counts minus baseline, expressed in percent of the similar result recorded in the parallel PCP control group. ...
Dioxane was then removed under reduced pressure. 200 ml of ethyl acetate was added to the remaining aqueous solution. The mixture was cooled in an ice-water bath. The pH of the aqueous later was adjusted to about 3 by adding 4N HCl. The organic layer was separated. The aqueous later was...
Deprotection of the amine of formula (III) is achieved under mild acidic conditions, such as addition onto a hydrogen chloride solution in an organic solvent such as dioxane, or with a TFA/DCM mixture, at low temperature ranging from 0° C. to room temperature. The reaction is stirred at ...
