Tetra-tert-butylcalix[4]arene (0.179 g, 0.242 mmol) and K2CO3 (0.066 g, 0.484 mmol) were added in DMF (2 mL) in a round-bottomed flask equipped with a magnetic stirrer. The mixture was gently heated until the calixarene had completely dissolved. 2-Mexylamino-4-methylamino-6-(3-bromom...
Y are as described above, to produce comb polymers of formula (I) without functionalization with ionic groups. The reaction is preferably done in the presence of CsF or CaH2/KF and a solvent at elevated temperature. The solvent is preferably dimethylacetamide (DMAc) or dimethylformamide (DMF). ...
The b-chlorovinylaldehyde III can be obtained from the ketone II and the Vilsmeier reagent (DMF-POCl3) using the general method described by Weissenfels (Z. Chem. 1966, 6, 471). The thiophene compound IV is obtained from III using the general method described by Weissenfels (Z. Chem., ...
When a functional group is termed "protected", this means that the group is in modified form to preclude undesired side reactions at the protected site. Suitable protecting groups for the compounds of the present invention will be recognized from the present application taking into account the leve...
Most polymers came in solid form and most were dissolved in DMF, except for nylons which were dissolved in m-cresol, and fluorinated polymers which were purchased as solutions. Polymer solutions were spin coated with the weight concentration (5-10%) and spin speed (1000-2000 rpm) adjusted to...
DMF = N,N-Dimethylformamid DMS O = Dimethylsulfoxid Et3N = Triethylamin HBSS = Hank'sche abgestimmte Salzlösung HEPES = N-[2-Hydroxyethyl]piperazin-N1-[2-ethansulfonsäure] HWB = Menschenvollblut IPA = Isopropylalkohol KHMDS = Kaliumhexamethyldisilazan LDA = Lithiumdiisopropylamid LPS =...
The compound from Preparation 3 (150 g) was dissolved in DMF (1.2 L) then the solution was cooled in an ice-water bath. To this solution was added K2 CO3 (138 g) portionwise and the mixture was left to stir for 30 min. Then allyl bromide (162 g) was added, the ice bath removed...
The N-alkylated product III may be prepared by addition of substituted acetate derivative (XCH2CO2R4; wherein X=leaving group) such as methyl bromoacetate to the salt of indole II prepared by addition of a base such as sodium hydride to the indole II in an organic solvent such as DMF. ...
in DMF (2 mL) was added NaH,(60% in oil, 60 mg, 1.5 equiv.). The suspension was stirred at 0° C. for 30 minutes followed by the addition of the benzyl chloride (230 uL, 2 equiv.). The resulting suspension was poured into H2O and extracted with Et2O (3×). The combined ...
