A two-step synthesis of corroles from dipyrromethanes and aromatic aldehydes has been achieved. Acid-catalyzed [2+2] condensation of (2,6-dichlorophenyl)dipyrromethane with electron deficient aldehydes in CH 2 Cl 2 followed by cyclization and oxidation in propionitrile or CH 2 Cl 2 , in the presence
Finely ground spruce wood (Picea abies (L.) Karst.) was incubated with various 9 commercial enzyme preparations; the incubation liquid was analysed for the presence and volume of uronic acids and neutral sugars. The tested enzyme preparations dissolved neutral and acid sugar from the woodpowder. The
