Microbial reduction of aromatic carboxylic acids.
Several benzoic, cinnamic and phenylacetic acid derivatives were screened with 20 micro-organisms, mainly fungi, for the reduction of their carboxylic function. For all organisms several compounds were reduced in fairly good yields up to 80% to the corresponding alcohol. No general rule could be established, concerning the substitution pattern, as to which compounds were transformed to the alco...
متن کاملThe reduction of cozymase by sodium borohydride.
Cozymase (diphosphopyridine nucleotide, DPN) has been assayed by a variety of biochemical and chemical methods (1). Among the simplest procedures has been the determination of the light absorption of reduced DPN at 340 rnp after reduction by sodium hydrosulfite. Since special precautions are required to remove completely the excess reducing agent which absorbs in this region, it appeared advant...
متن کاملDecarboxylative homocoupling of (hetero)aromatic carboxylic acids.
A variety of hetero(aromatic) carboxylic acids are shown to undergo decarboxylative homocoupling, mediated by a Pd/Ag system. This novel methodology for the synthesis of symmetrical biaryls avoids the use of haloarenes and organometallic compounds as starting materials.
متن کاملNew Procedure for the Preparation of Cellulose Esters with Aromatic Carboxylic Acids
Esterification of cellulose with subs t i tu ted or unsubs t i tu ted benzoic acids in t he system of pyridine containing methanesulfonyl chloride at various reaction conditions was investigated. Cellulose could be readily acylated with 2-nitro-, 3-nitro-, 4-nitro-, and 4-azidobenzoic acids to form: 0-(2nitrobenzoyl)cellulose (DS = 3), 0-(3-nitrobenzoyl)celhilose (DS = 3), 0-(4-nitrobenzoyl)cel...
متن کاملMicrobial transformation of esters of chlorinated carboxylic acids.
Two groups of compounds were selected for microbial transformation studies. In the first group were carboxylic acid esters having a fixed aromatic moiety and an increasing length of the alkyl component. Ethyl esters of chlorine-substituted carboxylic acids were in the second group. Microorganisms from environmental waters and a pure culture of Pseudomonas putida U were used. The bacterial popul...
