Facile synthesis of bis(indolyl)methanes catalyzed by α-chymotrypsin.
A mild and efficient method catalyzed by α-chymotrypsin was developed for the synthesis of bis(indolyl)methanes through a cascade process between indole and aromatic aldehydes. In the ethanol aqueous solution, a green medium, a wide range of aromatic aldehydes could react with indole to afford the desired products with moderate to good yields (from 68% to 95%) using a little α-chymotrypsin as c...
متن کاملAcetyl chymotrypsin and its reaction with ethanol.
A short report has recently been made (1) concerning the preparation of an acetyl derivative of chymotrypsin containing a single acetyl group of relatively high reactivity. The reaction, which may be carried out by any of several nitrophenyl acetates, begins with a rapid initial liberation of the free nitrophenol in practically mole for mole proportions to the total chymotrypsin present. Therea...
متن کاملIonic Liquid as an Efficient Medium for the Synthesis of Quinoline Derivatives via α-Chymotrypsin-Catalyzed Friedländer Condensation.
An efficient, convenient, and eco-friendly biocatalytic approach was developed for the synthesis of quinoline derivatives via the α-chymotrypsin-catalyzed Friedländer reaction. Interestingly, α-chymotrypsin exhibited higher catalytic activity in an ionic liquid (IL) aqueous solution as compared to that observed in our previous relevant study, which was conducted using an organic solvent, and a ...
متن کاملProperties of Casein Hydrolysate as Affected by Plastein Reaction in Ethanol-Water Medium
Zhang Y., Zhao X.-H. (2013): Properties of casein hydrolysate as affected by plastein reaction in ethanol-water medium. Czech J. Food Sci., 31: 559–567. Casein hydrolysate with in vitro ACE-inhibitory activity of 44.4% at 0.3 mg/ml was generated from casein by Alcalase and modified by the Alcalase-catalysed plastein reaction in an ethanol-water medium. Eight treated hydrolysates were prepared u...
متن کاملSubpattern formation during condensation processes on structured substrates
– We investigate the temporal and spatial development of condensation patterns on chemically patterned substrates. We find that droplets condense preferentially on lyophilic sites and are surrounded by a depletion zone where no further nucleation occurs. The size of the depletion zones can be tuned by the flow rate of the incoming gas stream. If the size of the depletion zones is in a suitable ...
