WebCompound 20 (50 mg, 0.063 mmol) is dissolved in DMF (20 ML) in the presence of 2,4, 6-tris- (dimethylaminomethyl)-phenol (1 mL, 3.7 mmol) and stirred at 50C overnight. After evaporation of the solvent, the residue is crystallised from dichloromethane: methanol to remove the excess of amine. After filtration, the porphyrins are re-dissolved in ... Web5. aug 2010 · In this article, we describe our results on boric acid-mediated synthesis of bis (indolyl)alkanes via the coupling of indoles with aldehydes and ketones under solvent-free conditions. Initially, the reaction was attempted by coupling of indole ( 1a, 2 equiv.) with benzaldehyde ( 2a, 1.2 equiv.) in the presence of 20 mol% of boric acid under ...
