Linalool Biotransformation with Fungi
Different fungal strains were screened for their ability to convert linalool into valuable flavour compounds. Aspergillus niger DSM 821, Botrytis cinerea 5901/02 and Botrytis cinerea 02/FBII/2.1 produced isomers of lilac aldehyde and lilac alcohol via 8hydroxylinalool as postulated intermediate. Linalool oxides and 8-hydroxylinalool accumulated as major products during fungal linalool biotransf...
متن کاملMagnesium halide-catalyzed anti-aldol reactions of chiral N-acylthiazolidinethiones.
[reaction: see text] Diastereoselective direct aldol reactions of chiral N-acylthiazolidinethiones occur in high yield with preference for the illustrated anti diastereomer. This reaction is catalyzed by 10% MgBr2.OEt2 in the presence of triethylamine and chlorotrimethylsilane. Yields range from 56 to 93% with diastereoselectivity up to 19:1 for a variety of N-acylthiazolidinethiones and unsatu...
متن کاملTheory of Hydrogen Migration in Organic–Inorganic Halide Perovskites**
Solar cells based on organic-inorganic halide perovskites have recently been proven to be remarkably efficient. However, they exhibit hysteresis in their current-voltage curves, and their stability in the presence of water is problematic. Both issues are possibly related to a diffusion of defects in the perovskite material. By using first-principles calculations based on density functional theo...
متن کاملREACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).
متن کاملSinglet oxygen production by chloroperoxidase-hydrogen peroxide-halide systems.
Singlet oxygen production in the chloroperoxidase-hydrogen peroxide-halide system was studied using 1268 nm chemiluminescence. With chloride or bromide ions, singlet oxygen is produced by the mechanism (formula; see text) (formula; see text) where X- is chloride or bromide ion. Under conditions where there is high enzyme activity and when Reaction B is fast relative to Reaction A, singlet oxyge...
